−	Wandora's Processing topic panel is used to run [http://processing.org/ Processing] scripts. Scripts can access Wandora's public API classes and methods. In effect, a Processing script can ask Wandora which topic is open, what are topic's associations, etc. Especially, a Processing script can access the topic map in Wandora. Wandora's Processing topic panel is a powerful tool for topic map visualizations and UI experiments. Processing topic panel starts with a menu option '''View > ~~Add topic~~ panel > Processing ~~topic panel~~'''. Below is a screen capture viewing Processing topic panel when you start it for the first time. Using Processing topic panel in Wandora requires no additional installations as Processing core is enclosed in Wandora's distribution packages.	+	Wandora's Processing topic panel is used to run [http://processing.org/ Processing] scripts.

If compilation fails, Wandora gives user an error message. if compilation is successful, Wandora loads the compiled class, creates an instance of it, and starts the applet. Running Processing applet is placed to Visual tab. Next image illustrates described execution model.
 '''Notice''': Wandora version 2012-04-30 has changed the templating mechanism of Processing scripts. Previous version of Processing topic panel injected user code into a predefined Java template that made the user code a PApplet. New version does '''not''' wrap user code into a predefined template but tries to compile the user code as such. All enclosed sample sketches have been adjusted to follow this change. If you have written your own Processing sketches and try to use them in Wandora version 2012-04-30 or above, you have to add wrapper explicitly into your sketch in order to compile and run sketches.
