In this article Rob Walling walks through the steps for creating a bar graph and dynamically adding hyperlinked 'hotspots' to drill into underlying data. The HTML Map element is used to mark the hotspots, which post back to the server to retrieve additional data. Along the way this article illustrates creation of a simple bar graph using the System.Drawing namespace, the dynamic creation of HTML Map elements, and the generation of post back events using the Page.RaisePostBackEvent() and Page.GetPostBackClientHyperlink () methods.
