FAQ
Treemap generator FAQs
What is a tree map chart generator?
It’s a tool that turns a list of categories and values into a treemap—rectangles sized by value. Ours adds AI to build a clean layout with readable labels, spacing, and sorting in one step.
How do I make a treemap online for free?
Open the tool, paste your data, and click Generate treemap. Use the free options to set label content and position, adjust stroke, round gaps, and export an image.
Can this treemap maker show both names and values?
Yes. Turn on labels and choose Name + value. You can position labels at the top, bottom, or center to fit your layout.
How do I sort categories by value?
Use the built‑in sort to order blocks by value descending. Sorting emphasizes the biggest contributors and makes comparisons easier.
Can I show percentages on treemap labels?
Treemaps display area by value. To show percentages, convert values to percent of total before pasting, or include percent in the label text alongside the value.
Does it support legends?
Treemaps usually rely on direct labels. For clarity, use Name + value and center labels; color can still distinguish groups if you provide custom colors.
What exports are available?
Download PNG or SVG for crisp results in slides, docs, and the web. You can also share a link or embed.
How does the AI help with setup?
AI interprets your intent, chooses label content and position, sorts by value, and sets spacing and aspect ratio for readability. You still have full control to tweak settings.
Is this a treemap chart generator for large datasets?
Yes, but readability matters. If many tiny categories appear, group small values or filter before import to keep labels legible.
What’s the difference between a treemap and a heatmap?
A treemap encodes value as area in nested rectangles; a heatmap uses color in a grid. Use treemaps for part‑to‑whole composition within fixed space.
