Recently I came across a few interactive chart controls. You can check them out and include them in your application if found useful.

Highcharts
I found Highcharts to be one of best chart controls, considering its “interactive” factor. You can check out the demos here and you’ll find that the chart is even displayed with some effects.

Highcharts are purely build using JavaScript’s and hence would load the charts and render them very effectively. You would also have hardly any impact on your page performance since the charts are not being created on the server side.

There is also a .Net version of this control that is coming up. You can check more details on that on CodePlex.

Highcharts are completely free as long as it’s used for Non-commercial purpose.

Google Chart Tools
This is another option that you have. You can check out the Google Chart API which would help you easily integrate the chart into your application.

There should definitely be some more interesting chart controls out there. I’ll update this list as and when I come across them. For now, have fun with these 🙂
