The example demonstrates how to inject custom script in the generated image map in order to show fading rollovers as well as some other features like server side events and direct stream to browser.

When the mouse hovers over the pie chart the appropriate image for the transport type will fade in on the left top of the page. When you click on a pie chart segment a server side event is triggered which modifies the pie detachment and changes the ImageUrl property of the sales analysis image at the bottom to an aspx page generating a direct stream to browser image.
