Frequently Asked Questions
What is a treemap chart?
A treemap is a data visualization that displays hierarchical or proportional data as a set of nested rectangles. Each rectangle's size corresponds to its value, making it easy to compare parts of a whole at a glance. Treemaps are commonly used for portfolio analysis, market share breakdowns, and file-size exploration.
How do I make a treemap online for free?
Go to MakeCharts, select the Treemap chart type, and add your category names and values. The treemap generates instantly. You can customize colors, labels, and layout, then download or share — all for free with no sign-up required.
How do I make a treemap chart in Excel?
In Excel 2016 and later, select your data, go to Insert > Charts > Hierarchy > Treemap. Excel will generate a basic treemap. However, customization options are limited compared to a dedicated tree map maker like MakeCharts, which also lets you export clean images and share links instantly.
How do I make a treemap in Excel if I have an older version?
Treemap charts were introduced in Excel 2016. If you have an older version, Excel does not support treemaps natively. In that case, an online treemap maker like MakeCharts is the fastest alternative — it works in any browser and requires no software installation.
What is the difference between a treemap and a tree map?
'Treemap' and 'tree map' refer to the same chart type — a rectangle-based proportional visualization invented by Ben Shneiderman in the 1990s. Both spellings are widely used interchangeably. MakeCharts supports both searches and lets you create either style with the same editor.
