This is an abstract JSP tag for displaying JFreeChart data in a web page. This class provides the mechanism for displaying any chart, along with an optional image map, with a simple JSP tag. This class is designed to be easily extended, and concrete implementations of this class can define the specific chart displayed through the createChart() method.
It is designed so that developers can easily create a page with a chart on it, without worrying about the servlets, JSPs or other syntax. A developer will need to only implement the createChart() method, add his tag to the TLD file (or create one), and add a simple one-line JSP tag to the web page.
