I came across a Del.icio.us network explorer that was built in Processing - a visualization toolkit. I took a look at the code, with the aim of extending the application to plot the structure of social networks. Processing has a Java like syntax, but I could not figure out where the classes were or where the code to make it run within an applet was. I still saw potential so I proceeded to download Processing to give it a try. I then went searching for a build script eg Ant or Maven. I got a surprise!!!!

Processing comes with its own IDE like environment called a SketchBook. Load any script and you can run it or export it to either a Java application or an applet. Both the applet and the required HTML files are generated. Very impressive
