The TreeMap control display hierarchical data as a set of nested rectangles. Hierarchical data are useful in varied walks of life and setups, be it family tree, programming, organization structure, or directories. Visualizing such a data and spotting information in them is a difficult task, especially if the data is huge. TreeMap control enables visualization of hierarchical data as nested rectangles on a limited space. It is useful in having a quick glimpse of patterns in large data and comparing proportions.


TreeMap control supports data binding to show hierarchy, and allows user to drill down the data further to numerous levels for detailed analysis. The control can be customized to display data in horizontal, vertical, and squarified layouts of constituting rectangles.
