Re: Best charting?

[Samuel Pelletier]

Ken,

You may want to look at d3, a javascript library for data visualisation with 
many widgets. It is like jQueryUI but specialized for data display. Search d3 
yourGraphType in google or explore the d3 sample page.

There are few very sharp commercial libraries I looked into but never used. 

I recommend you take the time to list your requirements because there are many 
options and it is sometime hard to find one that does everything...

Samuel
