A treemap is used to visualize hierarchical data as a set of nested rectangles. It is a data visualization tool for displaying data structured in a tree structure using nested rectangles. In this article, I’ll walk you through how to visualize a treemap using Python.
What is a Treemap?
A treemap is a data visualization technique used to visualize hierarchical data using nested rectangles. A treemap displays hierarchical data in such a way that each branch of the tree receives a rectangle which is filled with smaller rectangles as sub-branches.
Hope you now understand what treemaps are and the structure in which they display hierarchical data. In the section below, I’ll walk you through a tutorial on how to visualize treemaps using the Python programming language.
Visualizing a Treemap using Python
There are so many data visualization libraries in Python that we can use for visualizing treemaps, but the easiest way is to use the plotly library in Python. So below is how we can use plotly to visualize a treemap using Python:
