What is a treemap?

A treemap displays hierarchical data through nested rectangles that represent the composition of groups proportionally, making part-to-whole relationships evident.

In a treemap, the total rectangular area corresponds to 100%. Parent groups are defined by colors and labels, and their areas correspond to the total area of the subordinated smaller segments, i.e., the subcategories.

How to make a treemap with Vizzlo?

Create a colorful treemap to compare proportions among hierarchical data with ease:

• On the tab “DATA” of the sidebar, click on the button “GROUPS” to set the name and the color for your parent groups.
• Click on “EDIT CHART IN SPREADSHEET” to copy and paste your data into it. If necessary, adjust the number format (wheel icon) to match Vizzlo’s spreadsheet with your source.
• Click on any segment to edit it or change its color.
• Play with the layout settings on the tab “APPEARANCE” to choose the most efficient design for the representation of your data and increase the readability.

Pro tip: Hide the values to let the sizes of the parts/proportions speak for themselves. Or leave this option enabled to facilitate reading.
