Open Flash Chart is a charting component made by Flash. Open Flash Chart, is open source. It is free to use and you get the source code to fiddle with. You can create some really nice looking Bar Charts, Pie Charts, Area Charts and etc… easily. To use it, you simply need to include the Open Flash Chart in your HTML, and provide the data file on the server. The data file is either a text file, or a .php, Perl, Python, Java (or another flavour of dynamic) page.
