New TreeMap Data Visualization Control

Product 05/09/2013 by Thomas Hedén

The TreeMap control can effortlessly turn hierarchical or grouped data into meaningful representations that are colorized and visualized to suit your needs.
Treemaps display data as a set of nested rectangles, where the size of each rectangle corresponds to the size of the data value. The data can be organized in a hierarchy (as a tree), or simply grouped by specific values. Each branch/group is represented by a rectangle, which is then tiled with smaller rectangles representing sub-branches/groups. A leaf node's rectangle has an area proportional to a specified dimension on the data.
When the color and size dimensions are correlated in some way with the tree structure or groups, one can often more easily see patterns that would be difficult to spot in other ways. A second advantage of treemaps is that, by construction, they make efficient use of space. As a result, they can legibly display thousands of items on the screen simultaneously.
The TreeMap control is a part of our Forms concept for Genus Desktop.
