ASP.NET tree map

VIEW DEMOS

Overview

The ASP.NET Web Forms TreeMap Control is a data visualization tool which provides a simple and effective way to visualize flat or hierarchical data as clustered rectangles with a specific, weighted attribute determining the size of each rectangle. This treemap generator displays the data with more compact and space-efficient techniques. All the treemap elements are rendered using scalable vector graphics (SVG).

Leaf node

The treemap contains groups of data collection; each group has one or more leaf nodes. Each leaf node is displayed as a rectangle, sized and colored according to values that you assign.

Levels

Render any number of child items for each individual node in the treemap and they are categorized to form levels.

Color mapping

Categorize the nodes in the treemap by customizing their colors. Apply colors to the nodes by comparing their values with a desired numeric range or based on its underlying value.

Labels

Data labels in the ASP.NET Web Forms TreeMap Control are used to display more details about a particular item. Labels can be trimmed, hidden, or wrapped if the label width exceeds the item bounds.
