If you're looking for an open source dynamic Flash graphing system for your web-site you can find a really nice one called Open Flash Chart . The server side is PHP and text for the data with the graphs being displayed in Flash. I see no reason why the back end couldn't be written to support ASP, Python, Java script, or whatever. These charts are similar to Fusioncharts, very nice. I was thinking about making these, but I don't have the time so this just rocks!  

Fusioncharts is commercial, but they do have a free version for non-commercial use here .
