Thanks Nick.  Indeed a nice looking set of components, and quite comprehensive too.  Unofrtunately the license doesn't seem very applicable to an OSS project that may be used in downstream commercial products:

Good point Brian. I didn't pay attention to the license.  Have you looked at YUI?  They have a good charting component and is licensed under the BSD license.

In a reply to my blog I found a suggestion to use google charts after a quick review I found that the library requries an online acces to google servers so I think it is not suitable to be used in the component.

In my latest post, I noticed that I would try to find a way how to handle events in nvd3 unfortunately without any success. I asked on google group and I am waiting if someone replies with a solution. 

If not I think we should use flotcharts beacause it supports various chart types and event handling.

I suggest to use flot chart library for the component.  I'll take a look on YUI charting library Nick mentioned.

I have written a proposal of API for the chart component. I am going to introduce it shortly here and more details can be found on my blog.

  Hierarchical tag structure - the configuration of a chart is split into tags. Each of them customizes a part of the chart axes(min, max, label), legend and data(label, data, color, type) plotted. List of attributes to be customized is listed in the blog.

  Chart types - the component is going to support line, bar and pie chart at first.

  Data input - there are two ways of data input declarative (using a4j:repeat) and traditional (data model instance)

A data model proposal for the chart component can be found here.

There is a updated demo online and poll about data iteration style.
