Different Types of Treemaps and When They Are Best Used

Treemaps are a great way to display hierarchical data. But there are different types of treemap charts, and each one has its own strengths and weaknesses. In this article, we’ll take a look at the different types of treemaps, discuss examples of treemap charts, and when they are best used. Keep reading to learn more.

Defining Treemap Charts


Treemaps are a visualization of hierarchical data. They display the distribution of a variable (usually size) within a tree structure. The tree is laid out on a rectangular grid, with each branch represented by a rectangle, and the size of the rectangle representing the value of the variable for that branch. There are many different types of treemaps, but they all share some common characteristics. Each rectangle represents one node in the tree structure, and the size of each rectangle represents the value for that node. The rectangles are arranged in such a way that it is easy to see how the hierarchy relates to the values. Treemaps are best used when there is a lot of hierarchical data that needs to be visualized. They can be used to compare values between nodes or find specific nodes within the hierarchy.

Different Types of Treemaps

Treemaps are a visualization tool that can be used to display hierarchical data. There are three different types of treemaps: square, rectangular, and circular. Square and rectangular treemaps are the most common and can be used to display data in either a horizontal or vertical orientation. Circular treemaps are less common but can be used to display data in a radial orientation. Each chart type has its own set of benefits and drawbacks that should be considered when deciding which type is best suited for a given dataset. Square and rectangular treemap charts are best suited for datasets that have a small number of levels of hierarchy with few branches at each level. They are also well suited for datasets that have a lot of data values because they can display more data values than circular charts. However, square and rectangular charts can be difficult to read when there are many levels of hierarchy or when the branches at each level are very long. Circular treemaps are well-suited for datasets that have a large number of levels of hierarchy with few branches at each level. They also work well when displaying data values along a radial axis as opposed to a horizontal or vertical axis. However, circular treemaps can only display a limited number of data values and they can be difficult to read when the branch lengths vary greatly from one level to the next.

Advantages of Using Treemaps


Treemaps are particularly useful for visualizing hierarchical data. Each data point is a branch, and each branch has its own sub-branches. Some common examples of data are organizational charts and family trees. Treemaps are a great way to visualize this type of information because they show the relationships between data points. They also show how much space each data point takes up.

Disadvantages of Using Treemaps

These types of charts can be difficult to read if it’s too large. It can also be difficult to determine the percentage of each section if there are too many sections. They can be a hassle to create if the data is not already sorted in a tree structure.

Treemap charts are important because they can be used to display data in a compact and easy-to-read format. This can be helpful for understanding the overall structure of a data set, and for identifying patterns and outliers. Different types of treemaps can be used for different purposes, and they should be used when they are best suited for the task at hand.
