FAQ
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.
Can I use AI to generate a treemap automatically?
Yes. Describe what you want — for example, 'a treemap of my tech portfolio with five sectors' — and the AI will create a ready-to-use treemap with realistic values and distinct colors. You can then refine it manually or ask the AI to adjust colors, labels, or proportions further.
What file formats can I export my treemap in?
Free users can download treemaps as PNG images. Starter and above plans unlock SVG export, which is scalable and ideal for print, websites, and presentations that need crisp output at any size.
Can I embed a treemap on my website?
Yes. Plus and Pro plans include an embed code feature. Copy the snippet and paste it into any webpage, blog, or CMS to display a live version of your treemap without any additional tools.
How many items can a treemap display?
There is no hard limit on the number of items, but treemaps are most readable with 5 to 20 segments. With too many small values, labels can overlap and the chart becomes hard to interpret. Group minor categories into an 'Other' segment to keep your treemap clean and clear.
Is the MakeCharts treemap maker really free?
Yes. All chart types, including the treemap maker, are free to use with no sign-up required. Free accounts include limited AI credits to try AI-powered generation. Paid plans add more AI charts per month, SVG export, file upload, and embed codes for websites.
