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.)
