D3 charts interactive repository and learning center - javascript

I am new to d3 charts, Have worked on highcharts before, But for me, this looks like big guy. feeling difficult to understand. So I want to know, if there is d3 chart repositories on web (just like jquery plugin repository), So that I can download the matching chart and can do some minor changes, and that should work. Since I have only 2 months time to finish the project having full d3 charts. So I have planned like this.
Please guys, need to support and suggestions.
Thanks in advance.

NVD3 is a decent library for a variety of basic, ready-to-go charts:

Multiline js chart with support for irregular plot intervals

Does anyone know of a js chart that can plot multiple lines that can have different plot intervals? I can only find HighCharts but need an Open Source one. A great example of what I'm looking for is available on highcharts demo page:
http://www.highcharts.com/demo/combo-timeline
Thanks
I have use Google charts in the past, they are pretty easy to inject in your code, and they support multiline. Check em out.

D3.js or EXT js for data visualization and why?

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.

Javascripts for an Interactive network visualisation

I have been looking for some javascript code that I can use to create something similar to this.
I need something that can show the links between boxes when clicked on/hovered over. As of this point I have not yet been able to determine what the name of this particular type visualisation is.
I have already looked at:
Google Charts
d3.js
graphdracula
processing.js
Raphael
Protovis
MooWheel
PlotKit
You may want to focus in learning D3.JS because it seems to meet your requirements, and it does things very well.
The two vector graphic libraries you can focus are Raphael and D3.JS, but D3.JS is much more powerful with data binding. You can find a large amount of resources through the internet for D3JS.
Here are some of the tutorials that I think useful:
https://github.com/mbostock/d3/wiki/Tutorials
Examples gallery is here:
https://github.com/mbostock/d3/wiki/Gallery
Besides, D3js is the successor of Protovis, you can find this information at the following Wiki:
http://en.wikipedia.org/wiki/Protovis#Context
Google Charts may have some good features, but it's not a very active and well up to date as some other vector graphic tools.
For other libraries, I think should not spend much time.
Enjoy
Not exactly boxes, but more fluid network layout.

Graphs are pure HTML5, no dependancies on other libs, thus easy to integrate with any JS framework (such as jQuery). Uses Canvas for rendering, has full multi-touch support for navigation, interaction and exploration of data.
An example of network chart:
Charts come with extensive API and Settings, so you can control every aspect of the charts.

Using nvd3.js to draw a chart having stacked bar and line?

For the nvd3 library, I can find bar and line combo but not a Stacked bar and line combo. Actually i can't find any example done with other JavaScript library except for Google Visualization which I also try to avoid.
Any advise, sample code would be appreciated
Thank you
For all those searching for the nvd3 answer to this question in the future, I was able to do this using the code laid out in this discussion.
https://github.com/novus/nvd3/issues/341
Your best bet would be to turn to D3.js. NVD3 is a framework/wrapper for D3. D3 is super powerful. Just about anything you can imagine you can accomplish. I found that it sometimes comes with a bit of a steep learning curve - especially for things that are a bit out of the ordinary.
You can see from examples on their site that they have a lot of options. You will probably even be able to find the exact chart you're looking for. But going this route will require a bit more learning than what NVD3 requires.

Javascript library or framework for drawing charts on client side

I'm looking for an library, to generate charts on client side.
I found a lot, by searching on web and stackoverflow, like here
https://stackoverflow.com/questions/2227421/good-javascript-library-for-drawing-charts-using-json
or this very good collection:
http://sixrevisions.com/javascript/20-fresh-javascript-data-visualization-libraries/
There are so much alternatives, I'm a bit overwhelmed. Which one can use JSON data, which one is up to date, which one is easy to use (because I'm absolutely new on this topic), which one is robust, works on mobile phone (or not), which project is still alive, etc.
I need different chards, an line chart is mandatory. Also zoom in and zoom out is mandatory.
So I took a closer look on jqplot an flot.
Both providing zoom, but it looks like zooming is more an scaling. Which means: the granularity will not change by zoom in.
Because the graph will have a lot of data/points, i need to consolidate informations before sending them to the client. By zooming in, I need to rise the granularity, so the chart should be able to process new data for the zoomed area. (I hope I've made ​​myself clear.)
Thanks for any kind of attention.
Raphael.js http://raphaeljs.com/
HTML5 Graph http://chrisvalleskey.com/html5-graph/
Google Visualization API: http://code.google.com/apis/chart/interactive/docs/gallery.html
Flot: http://code.google.com/p/flot/
Unfortunately there is no helpful answer, so I like to write down, what i learned the last days for this question.
jqPlot and frot are supporting zooming at an basic level. That means, it's more an scaling.
By looking at the google groups for qjPlot and flot, the support for jqPlot is better (lot's of unanswered questions at the flot group).
jqPlot has an better axis-label-handling by zooming.
jqPlot also provides hooks. By using those hooks, it's seems to be possible to combine zooming and loading new JSON data in order to get an better granularity of the zoomed view.
