TreeMap control has numerous features to enable users display hierarchical data in a limited area, and analyze data by comparing the size of tree nodes (or nested rectangles). These are as follows:

• Hierarchical representation of data
  TreeMap control is an ideal tool to help users visualize and compare proportions in data values within a hierarchy.
  
• Layout
  TreeMap supports multiple display arrangements, where the tree branches can be shown as squares, horizontal rectangles or vertical rectangles.
  
• Customizable hierarchical levels
  TreeMap control enables users to vary the depth of data to be visualized and further drill down (or reverse drill down) the data for analysis and comparison.
  
• Customizable appearance
  TreeMap enables users to stylize the control and vary its appearance as per their preference. A set of varied color palettes are available to clearly display categories in a tree map chart.
  
• Data binding
  TreeMap can be bound to different data sources that contain data of varied size, allowing you to display such a data in limited rectangular area.
  
• Selection
  TreeMap enables selecting tree nodes and group of nodes to draw focus on specific data items in the hierarchical data.
  
• Optimum space utilization
  TreeMap is ideal for compact display and visualization of huge data. The nested rectangles and groups constituting the treemap chart adjust their size to fit the display area.
       
• Drill down the hierarchy
  TreeMap allows detailed analysis of hierarchical data by drilling down the data points on a mouse click. This is enabled by specifying the maximum depth of TreeMap hierarchy.
