[techtalk] graphical charts

[Nicki Handy]

I'm wondering if anyone knows the best way to program charts. I'm used to 
php and perl on linux, and I want to display data graphically. At one 
point, my company purchased Generator, a macromedia product for this that's 
similar to flash, but it's impossible to figure out b/c there's no 
literature/docs on it.

So, any languages and/or programs that are particularly friendly to that 
and linux?

Thanks,
Nicki
