Open Flash Chart
Charts are very popular and powerful tools for communicating important information in data centric applications. Flash is the right technology to create such charts because of their interactive and aesthetic features like animation, effects etc. There are lot of commercial charting libraries in the market but if you are looking for free open source flash charting library then you should consider Open Flash Chart.
I have seen its use in wordpress blog dashboard for showing blog stats

Open Flash charts reads data in JSON format which is a text format and is completely language independent. So you can use any language of your choice on server side to generate chart data in JSON format.
There are libraries available in lot of languages to help you generate JSON file for the chart to use here
