Tree Map Chart
In this article, we will explain how to create and customize a Annotation chart. So let's get started!
A tree chart is a graphical representation of a data tree that allows you to visually explore the hierarchical relationships between different data points. In a tree chart, each node can have one parent (except for the root node, which has no parents) and zero or more children. The root node is typically the starting point of the tree, and all other nodes branch off from it.
Here is an example of a table map chart and sample data:
This tree map chart shows data on the populations and per-capita of various counties within different cities and countries. The rectangles are nested to represent the hierarchical structure of the data, with the size of each rectangle representing the population and the color representing the per-capita of the corresponding region . The user can hover over each rectangle to see the name and metrics of the region.
The configuration shown illustrates how to map the two nodes, population and per-capita to create a tree map chart:
In addition to mapping nodes, to create a tree chart, you will need to assign values to each node that determine its size and color. The sizes and colors are relative to all other nodes in the chart, so you can use them to highlight certain nodes or groups of nodes.
If a node is a leaf node (i.e., it has no children), you can specify its size and color. If it is not a leaf node, it will be displayed as a bounding box for leaf nodes. This helps to visually group nodes and make it easier to understand the relationships between them.
The default behavior of a tree chart is to move down the tree when a user left-clicks a node, and to move back up the tree when a user right-clicks the chart. This allows you to easily navigate through the tree and explore the data.
- Remember to set one node as the root with "null" in the parent node column.
- Make sure that all parent and child nodes are unique, with no self-references. For example, if mapping New York State to New York City, use "New York City" as the child node and "New York State" as the parent node.
- Make sure that all child nodes have a parent node.
Infinity offers many customization options for your table map chart. To access these options, click on the customize tab in the chart builder screen. This will display a list of customization options.

There are a few useful tips to keep in mind when using tree map charts:
- 1.Make sure to clearly label the chart and include a descriptive title.
- 2.Use a clear and readable font for the labels and data values to make it easier for readers to understand the chart.
- 3.Use appropriate coloring and shading to differentiate between the different data points and to make the chart visually appealing.
- 4.Consider using hover-over text or other interactive elements to help users explore the data and understand the relationships between the different data points.
