This example demonstrates the application of the dynamic image map, automatically generated and updated at client side on every asyncronous callback.
 
The dynamic image map allows for processing of the mouse over and mouse out events for the separate elements of the chart.
 
The hover effect is achieved by delegating the mouse over and out events to the server. The event log listbox is updated by intercepting the mouse over and out events on the client side.
