Charts tool

[contracer11]

Hi:
I'm using gnuplot freeware tool to create charts.
Do you know any good tool to create charts
with best visual effects than gnuplot ?

I create great looking charts in Excel 2007 and export them all as gifs directly to SharePoint with some code. Then I have a table that I created in SharePoint Designer to reference them and pull them in for a dashboard view.

Works great!
