I am building a dashboard using JS, that will show users plots of their sales data. Can you suggest a js library, which:
Can plot many points (100k for instance or even more)
Interactive
Supports SSR without losing interactivity (if it’s possible. I just assume that the only way to load this number of data without hurting UX is SSR)
Optional: works with React
Many thanks for any help!
There's probably many options but one could be Victory Chart. The library is built on top of D3.js and is heavily customizable. For your large dataset, I can think of one solution I used that is documented here.
One reason I'd suggest Victory is because they have a nice support community here.
I read many blog posts about that topic, here's one that compares a few "big" chart libraries with React Components.
For time series, I'd suggest having a look at this library.
If nothing works with large datasets, I think that your best option would be D3.js (with or without a React implementation).
I want to visualize a Neo4j database in a graphical application. (I'm doing this primarily as a learning exercise).
I want it to behave almost identically to the visualization in Neo4j's WebAdmin: When the graphic appears, I want to see the nodes moving around as they settle into their final locations, and I want the user to be able to click and drag node icons around the screen and have them stick where they are dropped, with the rest of the graph adjusting to account for the change.
I have two questions.
What are the technical terms for the three requirements crudely described in the paragraph above?
I'm a Java programmer with no experience in JavaScript, but I'm thinking that, with this project, it's time to get some - sigma.js in particular seems very powerful and relatively simple. However, ultimately this needs to be done within a Java Swing application, and while I know there are various containers I can use to embed JS/HTML content into Swing, still it seems that a pure Java solution would be ideal, and I'm curious about any frameworks that might make this possible. I'm looking into Gephi now, but it doesn't seem anywhere near as powerful or as simple to use as sigma.js. Am I wrong in this assumption?
To summarize the second question: Which would be the better investment of my time: Learning sigma.js and the various JS frameworks (which will require me to get comfortable with JS in general), or learning to use Gephi in Java? (assuming I have a general and long-term interest in graph visualization)
Java visualization
Gephi does provide a toolkit for Java and Python which doesn't contains the UI modules, so unless you want to use Gephi itself to visualise your network you cannot embed its UI in your Java/Swing application as long as I know.
The toolkit contains all the algorithms and plugin infrastructure so if you want to use some of their analysis tool embedded in your app you can use that, otherwise I don't think it's your case.
There are other Java options if you want for graph visualisation here: Java graph library for dynamic visualisation
About Gephi and sigmaJS
IMHO Gephi is far more powerful than sigma.js: it has full SNA tools, multiple layouts, a data editor, exporters, plugin-systems...
One important factor is also the size of the dataset you want to visualise: while sigmaJS can handle up to 500 nodes in the view, Gephi can layout easily 50000 nodes with GPU support as well.
Gephi is a scientific tool made for people that don't want to code to visualise a network and it does it's job. SigmaJS is one of many JS solutions to visualise graphs on a web page.
You can always export to sigmaJS from Gephi with a plugin.
What's better?
At the end of the story I guess the tool you are going to use will depends on:
do you have to visualise a big dataset? -> Java solutions will win for big ones
do you need to distribute it easily? -> Web app / SigmaJS wins for distributed
do you want to have a full integration with your app? -> Java wins
The best one I've found is Keylines, but its not cheap.
Gephi is OK, but the last time I looked it did not support Neo4j 2.0
If your a programmer Neo4j is open source, so you can fork the repository on Git and use that (you will have to check the licencing model before you commercialise any product though)
I am asking about some JavaScript library or API that I can integrate it in my winjs/HTML Windows store application.
I would like to connect it with my data to render some awesome charts or pies etc.
If someone have any library in mind it will be helpful for me.
Basically you can use any of the diverse Javascript graphing libraries out there. It will depend on what you want to achieve but here's a couple of libraries I found to be of very high quality:
http://g.raphaeljs.com/ (very straightforward)
http://d3js.org/ (more power, more complexity)
http://www.flotcharts.org/ (nice plugin system)
In case charting is an important part of your app, this commercial library may be for you http://www.highcharts.com/
I also found this very extensive list which has even more charting libraries on it but didn't sift through it.
If you are looking for a solution built specifically for Windows 8 HTML and WinJS, then look at the RacControls for Windows 8. They contain a wide array of charts and graphs, as well as SparkLines (coming in beta in the next couple of days) for very lightweight rendering of your data visualizations. If you are looking for Cross Platform, Kendo UI DataViz has many of the same options.

Would anyone recommend a particular JavaScript charting library - specifically one that doesn't use flash at all?
There is a growing number of Open Source and commercial solutions for pure JavaScript charting that do not require Flash. In this response I will only present Open Source options.
There are 2 main classes of JavaScript solutions for graphics that do not require Flash:
Canvas-based, rendered in IE using ExplorerCanvas that in turns relies on VML
SVG on standard-based browsers, rendered as VML in IE
There are pros and cons of both approaches but for a charting library I would recommend the later because it is well integrated with DOM, allowing to manipulate charts elements with the DOM, and most importantly setting DOM events. By contrast Canvas charting libraries must reinvent the DOM wheel to manage events. So unless you intend to build static graphs with no event handling, SVG/VML solutions should be better.
For SVG/VML solutions there are many options, including:
Dojox Charting, good if you use the Dojo toolkit already
Raphael-based solutions
Raphael is a very active, well maintained, and mature, open-source graphic library with very good cross-browser support including IE 6 to 8, Firefox, Opera, Safari, Chrome, and Konqueror. Raphael does not depend on any JavaScript framework and therefore can be used with Prototype, jQuery, Dojo, Mootools, etc...
There are a number of charting libraries based on Raphael, including (but not limited to):
gRaphael, an extension of the Raphael graphic library
Ico, with an intuitive API based on a single function call to create complex charts
Disclosure: I am the developer of one of the Ico forks on github.
If you're using jQuery I've found flot to be very good - try out the examples to see if they suit your needs, but I've found them to do most of what I need for my current project.
Additionally ExtJS 4.0 has introduced a great set of charts - very powerful, and is designed to work with live data.
Check out http://www.highcharts.com !
Highcharts is a charting library written in pure JavaScript, offering an easy way of adding interactive charts to your web site or web application. Highcharts currently supports line, spline, area, areaspline, column, bar, pie and scatter chart types.
It maybe not exactly what you are looking for, but
Google's Chart API is pretty cool and easy to use.
There is another javascript library based on SVG. It is called Protovis and it comes from Stanford Visualization Group
It also allows making nice interactive graphics and visualizations.
http://vis.stanford.edu/protovis/ex/
Although it is only for modern web browsers
UPDATE: The protovis team has moved to another library called d3.js (Data Driven Documents) as they said:
"The Protovis team is now developing a new visualization library, D3.js, with improved support for animation and interaction. D3 builds on many of the concepts in Protovis"
The new library can now be found in:
http://mbostock.github.com/d3/
UPDATE 2:
"Rickshaw" is a JavaScript toolkit for creating interactive time series graphs. Based on d3.js that simplifies a lot the work with d3.js although is a little bit less powerful.

I was recently looking for a javascript charting library and I evaluated a whole bunch before finally settling on jqplot which fit my requirements very well. As Jean Vincent's answer mentioned you are really choosing between canvas based and svg based solution.
To my mind the major pros and cons were as follows. The SVG based solutions like Raphael (and offshoots) are great if you want to construct highly dynamic/interactive charts. Or if you charting requirements are very much outside the norm (e.g. you want to create some sort of hybrid chart or you've come up with a new visualization that no-one else has thought of yet). The downside is the learning curve and the amount of code you will have to write. You won't be banging out charts in a few minutes, be prepared to invest some real learning time and then to write a goodly amount of code to produce a relatively simple chart.
If your charting requirements are reasonably standard, e.g. you want some line or bar graphs or perhaps a pie chart or two, with limited interactivity, then it is worth looking at canvas based solutions. There will be hardly any learning curve, you'll be able to get basic charts going within a few minutes, you won't need to write a lot of code, a few lines of basic javascript/jquery will be all you need. Of course you will only be able to produce the specific types of charts that the library supports, usually limited to various flavors of line, bar, pie. The interactivity choices will be extremely limited, that is to say non-existent for many of the libraries out there, although some limited hover effects are possible with the better ones.
I went with JQplot which is a canvas based solution since I only really needed some standard types of charts. From my research and playing around with the various choices I found it to be reasonably full-featured (if you're only after the standard charts) and extremely easy to use, so I would recommend it if your requirements are similar.
To summarize, simple and want charts now, then go with JQplot. Complex/different and not pressed for time then go with Raphael and friends.
jqPlot is great. If your requirements are fairly "normal" and you just want to draw some charts, you're probably overwhelmed by the quantity of js charting options. Assuming you don't want to do hours of research, just go with jqPlot as it's probably your best bet. It covers most use cases for most people well. Some of the alternatives are specialised on a certain type of chart or built with a certain use case in mind.
As some kind of late answer, try d3.js
http://mbostock.github.com/d3/
It's the continuation of protovis.
The big difference to flot is in the number of features supported.
Though flot may be simpler, d3.js is definitely more powerful.
Flotr is another, pure Javascript chart-library based on Prototype and inspired by Flot
Try PlotKit
I'd recommend gRaphaël for pure JavaScript charting along with the pure JavaScript vector graphics library it's built on (Raphaël).
gRaphaël currently supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.
a framework: http://www.simile-widgets.org/
a basic: http://www.filamentgroup.com/examples/charting_v2/index_2.php
good looking: http://www.highcharts.com/
Another is RGraph: Javascript charts and graph library:
http://www.rgraph.net
Canvas based so it's fast and there's roughly 20 different chart types. It's free for non-commercial use too!
My favourite (flot) has already been mentioned.
But be sure to investigate Ortho.
It is excellent for tree charts and timelines.
There is a lot of activity in the dojo charting library, and what is great I am using it inside an AIR application without problems too, pretty cool!
See for example there http://www.sitepen.com/blog/2008/05/27/dojo-charting-event-support-has-landed/
Check out Google Visualization API, which is kind of a generalization of the simpler Chart API
http://code.google.com/apis/visualization/documentation/gallery.html
Has very cool interactive options including maps, gauges, and charts.
We just bought a license of TechOctave Charts Suite for our new startup. I highly recommend them. Licensing is simple. Charts look great! It was easy to get started and has a powerful API for when we need it. I was shocked by how clean and extensible the code is. Really happy with our choice.
Try the MIT simile timeline which could be made into a chart - http://simile.mit.edu/timeline/
or the final one, http://code.google.com/p/gchart/
Not a Javascript library but it may be a suitable alternative - check out Google Charts where you can generate charts by passing querystring data to their web service.
Take a look at Bluff. It's a JavaScript port of the Gruff graphing library for Ruby.
Protochart is all you need
Sencha acquired Raphael and now their charts are pure javascript as of version 4. Emprise and HighCharts mentioned above are my two favorites.
http://www.sencha.com/
For the more unusual charts: http://thejit.org/
I can recommend ArcadiaCharts. A brand-new professional charting library for JavaScript and GWT. Runs in all browsers without plugins. Easy and fast to use: creates great looking charts with just a few lines of code.
Free for non-commercial use.
Fusion charts has a new javascript/jquery library that looks promising.
In case what you need is bar chart only. I published some code I've been using in an old project. Someone told me the VML implementation is broken on recent versions of IE, but the SVG should work just fine. Might be getting back to the project and release some serverside renderers I already have and maybe WebGL rendering layer. There's a link: http://blog.conquex.com/?p=64
Probably not what the OP is looking for, but since this question has become a list of JS charting library options: jQuery Sparklines is really cool.
Check out ZingChart HTML5 Canvas, SVG, VML and Flash Charts. Very powerful and compatible library. I'm on the Zing team - mention us on twitter #zingchart or shoot any questions to support#zingchart.com.
There are many Web sites that include clickable maps that highlight regions on mouseover and allow the user to narrow down a selection from a world map view to a continent level. Here is an interesting example: davidlynch.org.
Many of these clickable maps are implemented with HTML image maps, while another option is to use for example Google's GeoChart API. Concerning the HTML image maps option, I'm wondering where people get all the 'raw data', all the country and regional border polygons. Is there a free resource for that? Concerning the Google GeoChart option, I'm wondering if that is scalable or if the number of API calls are somehow limited?
Does anyone have some advice on the availability of a free library that allows a straightforward implementation of clickable maps with customizable regions?
Well it is not really a problem which could be tagged 'geocoding'.
Since I have been playing with Raphael.js these days, I thought of this lib while reading your question title. I also remember Wikipedia commons hosted a SVG map of the world. Raphael helps you manipulate svg files, so that could be a nice way to go.
Anyway, after searching whith the criteria 'raphael' I found a conversation matching your request, exactly. So there it is : http://groups.google.com/group/raphaeljs/browse_thread/thread/46b5402c677ce274/7ff6a6a8d8f5f9fa?pli=1
There are some utility scripts, as well as the link to the svg world file mentioned above and a live examples (and links to Stack Exchange topics).
Sure there is work to do, and it may be easier to call directly the google api.
In my experience of the gmaps API, you have to make many requests per second to be blacklisted by google. Like when you launch a heavy batch geocoding tool. So it depends of your project but I would consider quite safe to use it even if your page is popular.
[EDIT] : There is now a live demo on RaphaelJs website.
[EDIT again]: And now a complete production workflow based on Python and Raphael exists : Kartograph. It's really young but looks promising.
Check this out. Seems to serve your requirements and offers a bit more:
Google Maps with Clickable Regions
http://codecanyon.net/item/google-maps-with-clickable-countries/3186942
I second the raphael.js, it is a nice library to draw the shapes with all kinds of user interaction. As an example, you may look at this project, which is a vector map of Russia, implemented on top of the Raphael.js. It allows highlighting the regions programmatically.
There are two libraries I can recommend without doubt: 1. d3JS and 2. Raphael JS
The latter is what I was using for writing my
clickable map generator web application - Make a Clickable Map
d3JS has a steeper learning curve, but you can do way more things with it than Raphael. On the other hand, Raphael is easier to pick up and is fun to work with.
