Description: Chart Enabling Web Object Framework (Cewolf) can be used inside a Servlet/JavaServer Pages (JSP) based web application to embed various complex graphical charts (e.g. line, pie, and bar chart, plots, etc) into a web page. Cewolf uses its rendering engine to render the final chart image into the client`s response stream. Cewolf consists of one servlet, which handles the chart rendering and a tag library that translates the chart definition included in the JSP into HyperText Markup Language (HTML) `img` tag and consults the rendering servlet for retrieval of the appropriate chart.
