TreeMapViewer

A delphi program to visualize hierarchical data through treemaps. The implementation is based on two papers Tree visualization with tree-maps: 2-d space-filling approach by B. Shneiderman and Squarified treemaps by D.M Bruls, C. Huizing and J.J. van Wijk. Both the original slice-and-dice and squarify algorithm are implemented succesfully. The user can select a text file with hierarchical data or visualize the hard disk. Several features which make the reading of the treemaps easier, like a cascading option, are added.

The lighter the color of the tile, the higher the object is in the hierarchy. Mouse over gives information about the tile. Yellow line means direct parent, Red lines are higher parents of the object. Of course the colors are customizable, also two different rendering modes are implemented. Plain but fast and shaded but slow(er).
