toolkit for development of 2D structured graphics

Piccolo is a toolkit for creating graphical applications in Java, with visual effects such as zooming, animation and multiple representations. It supports the development of 2D structured graphics programs, in general, and Zoomable User Interfaces (ZUIs), in particular.

Piccolo allows programmers to build structured graphical applications without worrying about the low level details. The infrastructure provides efficient repainting of the screen, bounds management, event handling and dispatch, picking (determining which visual object the mouse is over), animation, layout, zooming, and more.
