I want to create an animated pie chart in JavaScript. I have done some R&D myself and found the Google Charts API.
But my major concern is the actual data is sent to the Google server for creating the charts. I am concerned about sending my data to a third party.
If you're concerned about sharing data with a third party, you might consider an offline charting library, like ZingChart. It gives you the ability to create animated pie charts quickly and easily without the need to transfer any of your data to a third party. This charting library works offline, and is dependency free. There are a number of animations that can be applied to the various types of charts, including pie charts. Check out this animated pie chart demo.
Lists of the different animation effects, methods, and sequences can be found on the animation docs page.
I'm a member of the ZingChart team, so please feel free to ask if you have any questions! :)
I suggest you use jPlot! You can do Pie and Donut Charts, Bar Charts, Line Charts and much more!. See the API here.
A DEMO here.
D3pie is also a good option
They also have a generator that you can use if you want to build your an example and work from there.
I am trying to learn D3 JS and how it can be applied in current application.I am new to this application.
While going through the application I found that there is already a feature providing data visualization in the form of graphs using EXT Js charts.
Could anybody help me understand the advantage of data visualization using ext js over D3 JS and is there any reason for going with one over other? Thanks in advance.
ExtJS is a commercial web app framework for many things including data visualization. D3.js is an open source low level library for creating svg-based charts.
The first question you need to figure out is if you only want charts or all the features that come with ExtJS.
If you just want to draw standard charts (bar, line, area, pie etc.) you may consider using highcharts, google charts, or a higher level library on top of d3.js such as nvd3.js or Rickshaw since they are easier to use. Otherwise if you want a very non-standard and customized chart, d3.js is very powerful for implementing any possible kind of visualization.
D3 is just for visualization, ExtJS is a full framework that hast a lot of other components (grids, windows, layouts, etc...).
Also ExtJS doesn't get well with other libraries, since it overrides several things in the global CSS.
Therefore, if you have a full page that has more than just graphs... feel free to use ExtJS for the whole page, but if you already have something else on the page, then go for D3.
This is my problem: For a school project we are trying to create a directed graph and make it fit in a typical html website. We figured out it had to be written in javascript, because a java applet isn´t an option. So this is how it should look like: image.
The data visualised in the graph will be gathered from some xml files.
We took a look at flare and some other packages, but real thing is making a two-way link between the nodes (where the thickness of the arrow represents importance) in our graph. Making the whole thing moveable is also required.
Any ideas? Thank you.
Have a look at jsPlumb - a not featurerich but easy customizable jQuery Plugin for directed graphs

Has anyone seen an open-source library that produces charts similar to Github.com's commit timeline charts? Check out this profile (picked one at random) and note the bar graphs below each project.
I've been trying to dominate Flot into behaving correctly but it just doesn't have the flexibility of formatting options to come up with a decent clone. Personally, I'd prefer a Javascript implementation but I'm open to looking at server-side stuff as well.
Definitely has to be a stand-alone implementation, the application is headed to a network separated from the Internet, so Google Charts API is out of the question.
I'd suggest using jQuery Sparklines. You'll need to create two separate graphs and position them on top of one another (one for the blue bars, another for the gray bars). You'll also need to make the dotted line/legend an image, but github also uses an image for that.
Here are some decent values to get you started:
EDIT: I originally overlapped two separate sparklines with relative positioning, but it would be better to use the "composite" option to draw two graphs on the same canvas.
I want to create a pie chart in JavaScript. On searching I found the Google Charts API. Since we are using jQuery I found that there is jQuery integration for Google Charts available.
But my problem is here the actual data is sent to the Google server for creating the charts. Is there a way to prevent the data from being sent to Google? I am concerned about sending my data to a third party.
Flot
Limitations: lines, points, filled areas, bars, pie and combinations of these
From an interaction perspective, Flot by far will get you as close as possible to Flash graphing as you can get with jQuery. Whilst the graph output is pretty slick, and great looking, you can also interact with data points. What I mean by this is you can have the ability to hover over a data point and get visual feedback on the value of that point in the graph.
The trunk version of flot supports pie charts.
Flot Zoom capability.
On top of this, you also have the ability to select a chunk of the graph to get data back for a particular “zone”. As a secondary feature to this “zoning”, you can also select an area on a graph and zoom in to see the data points a little more closely. Very cool.
Sparklines
Limitations: Pie, Line, Bar, Combination
Sparklines is my favourite mini graphing tool out there. Really great for dashboard style graphs (think Google Analytics dashboard next time you login). Because they’re so tiny, they can be included in line (as in the example above). Another nice idea which can be used in all graphing plugins is the self-refresh capabilities. Their Mouse-Speed demo shows you the power of live charting at its best.
Query Chart 0.21
Limitations: Area, Line, Bar and combinations of these
jQuery Chart 0.21 isn’t the nicest looking charting plugin out there it has to be said. It’s pretty basic in functionality when it comes to the charts it can handle, however it can be flexible if you can put in some time and effort into it.
Adding values into a chart is relatively simple:
.chartAdd({
"label" : "Leads",
"type" : "Line",
"color" : "#008800",
"values" : ["100","124","222","44","123","23","99"]
});
jQchart
Limitations: Bar, Line
jQchart is an odd one, they’ve built in animation transistions and drag/drop functionality into the chart, however it’s a little clunky – and seemingly pointless. It does generate nice looking charts if you get the CSS setup right, but there are better out there.
TufteGraph
Limitations: Bar and Stacked Bar
Tuftegraph sells itself as “pretty bar graphs that you would show your mother”. It comes close, Flot is prettier, but Tufte does lend itself to be very lightweight. Although with that comes restrictions – there are few options to choose from, so you get what you’re given. Check it out for a quick win bar chart.
jqPlot looks pretty good and it is open source.
Here's a link to the most impressive and up-to-date jqPlot examples.
Tons of great suggestions here, just going to throw ZingChart onto the stack for good measure. We recently released a jQuery wrapper for the library that makes it even easier to build and customize charts. The CDN links are in the demo below.
I'm on the ZingChart team and we're here to answer any questions any of you might have!
$('#pie-chart').zingchart({
"data": {
"type": "pie",
"legend": {},
"series": [{
"values": [5]
}, {
"values": [10]
}, {
"values": [15]
}]
}
});

A few others that have not been mentioned:
For mini pies, lines and bars, Peity is brilliant, simple, tiny, fast, uses really elegant markup.
I'm not sure of it's relationship with Flot (given its name), but Flotr2 is pretty good, certainly does better pies than Flot.
Bluff produces nice-looking line graphs, but I had a bit of trouble with its pies.
Not what I was after, but another commercial product (much like Highcharts) is TeeChart.
Chart.js is quite useful, supporting numerous other types of charts as well.
It can be used both with jQuery and without.
There is a new player in the field, offering advanced Navigation Charts that are using Canvas for super-smooth animations and performance:
https://zoomcharts.com/
Example of charts:
