The ASP.NET Core Blazor TreeMap is a feature-rich component used to visualize both hierarchical and flat data. Customize the look and feel of the tree maps by using built-in features like color mapping, legends, and label templates.
A treemap contains groups of data collections. 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.
Render any number of child items for each individual node in the a tree map and they are categorized them to form levels.
Categorize the nodes by customizing their colors based on the underlying values.
Apply colors to the nodes by comparing their values with a desired numeric range. For example, colors can be applied to countries based on their population growth.
Use equal color mapping to differentiate an item’s fill based on its underlying value and color. For example, colors can be applied to states based on a winning candidate.
Apply colors to the nodes by comparing their values with desaturation color order. For example, transparent color can be applied to countries based on their population variation from higher to lower.
Data labels in the Blazor TreeMap component 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.
Render any HTML element as a label for the nodes in the a tree map.
Zoomable Blazor TreeMap component provides support to drill the parent items to have a more detailed look at their child items.
Use legends to add additional information for interpreting a treemap with various colors, shapes, or other identifiers.
The Blazor TreeMap component provides two types of legend, default and interactive.
A default legend contains swatches of symbols with descriptions to denote the categories of items.
An interactive legend is used to find the range of an underlying item’s value on mouse over.
Position the legend to top, bottom, left, or right of the a tree map.
Change the legend item shape to a circle, rectangle, or another built-in custom shape to represent the items.
Use different layouts types to view the child nodes in effective ways.
Visualize the data in the form of square-like rectangles with best aspect ratio in this layout.
Visualize the data in the form of long, thin rectangles that can be displayed either vertically or horizontally with high aspect ratio in this layout.
This layout creates rectangles with high aspect ratio and displays them horizontally.
This layout creates rectangles with high aspect ratio and displays them sorted vertically.
When the mouse hovers over the an item, the interactive Blazor TreeMap component displays details about the item’s values in a tooltip.
Select a particular shape on mouse click and highlight on mouse over to bring it to the center of attraction over other items in the a tree map.
Add a title and subtitle to visualize additional information on a tree map. You can customize the font and alignment of the titles and subtitles.
Customize the look and feel of a tree map by changing the fill color, background, border, and opacity of the items.
Change the fill color, background, border, and opacity of the nodes to customize the appearance.
Enhance the readability by customizing the gaps within the groups of leaf nodes.
Built-in palettes with customizable options are available by default.
You can render the tree map elements like nodes, headers, labels, and legends in the right-to-left direction.
Exports the a tree map to a PDF document or in image formats such as SVG, PNG, and JPEG in client-side.

Print the rendered treemap directly from the browser.
The interactive TreeMap component supports touch interactions.
All the tree map features will work on touch devices with zero configuration. Use touch features such as tooltips, drill-down, selection, and highlighting without any customization.
You can view the Blazor TreeMap component on various devices. Hide specific elements in a tree map for particular screen sizes by making a very minimal change in the tree map events.
You can render the TreeMap component in all modern browsers.
