The html of chart does not validate on w3c. It has over 30 errors.
I have changed function RenderChartHTMLALL in FusionCharts.vb to make code that validates.
This works for asp.net but you can use code for anything else because it generates html.
It works in Firefox, Internet Explorer, Opera, Chrome ... You can test it and let me know if you find any bugs.
