FAQ
Frequently Asked Questions
What is a nested treemap?
A nested treemap is a visualization that displays hierarchical data as a set of rectangles, where each parent category contains proportionally sized child rectangles. The area of each rectangle represents its value relative to the whole, making it easy to compare parts within a group and across groups simultaneously.
Is this nested treemap maker really free?
Yes. You can create, customize, and download treemap charts for free with no account required. Free AI credits are included so you can try AI-powered generation right away. Paid plans unlock more AI credits, file upload, and embed codes.
How do I make a treemap chart with my own data?
Click 'Add item' in the data panel, enter your category names and values, then assign a color to each row. The treemap updates live as you type. You can also paste data from a spreadsheet or upload a CSV file on Pro.
Can I create a nested treemap with multiple levels?
Yes. You can group items by assigning them to parent categories using the data table. The treemap maker renders each group as a colored region with sub-rectangles sized by value, giving you a true nested hierarchical view.
What file formats can I export my treemap in?
You can download your treemap as a PNG for use in presentations, documents, and social posts, or as an SVG for print-quality output. Embed codes for websites are available on Plus and above plans.
How does the AI treemap generator work?
Type a plain-language description of the data you want to visualize — for example, 'Show global energy consumption by source and region' — and the AI builds a complete nested treemap with realistic values, colors, and labels. You can then edit any element manually.
Can I use the treemap maker without signing up?
Absolutely. No account or credit card is needed to create and download a treemap chart. Sign up only if you want to save your charts, access AI features, or unlock advanced export options.
What is the best use case for a treemap chart?
Treemaps are best when you need to show part-to-whole relationships within a hierarchy — like budget allocation across departments, market share by company within a sector, or file sizes across modules in a codebase. If the ranking or trend over time matters more, a bar or line chart may serve you better.
How do I customize labels in the treemap?
In the Display Settings panel, toggle labels on or off, then choose to show the name, the value, or both. You can also control label position (top, center, or bottom) and font size to keep the chart readable at any size.
Does MakeCharts work on mobile for treemap creation?
Yes. The nested treemap maker is fully responsive and works on phones and tablets. You can create, edit, and export treemap charts from any device without installing anything.
