ConvexClip (Macrofocus TreeMap API for Swing SpecificationA good and efficient starting point is the use of the SwingTreeMap component. It contains all the information to get started within minutes!To use this API, please make sure you have at least (this is the absolute minimum) the macrofocus-treemap-swing.jar, macrofocus-treemap.jar, macrofocus-common.jar, macrofocus-visualization.jar, and macrofocus-slider.jar libraries in your class path.)
