What is a treemap maker?

A treemap maker lets you create a chart where data is represented as nested rectangles, larger rectangles mean larger values. AECharts lets you paste data, customize colors and styling, and export and use in PowerPoint or Google Slides, useful for presentations, reports, and infographics.

What kind of data works best in a treemap?

Treemaps work best for hierarchical data with two levels: a category grouping and individual items within each category, each with a numeric value. Examples include budget breakdowns by department and line item, revenue by product category, or market share by sector and company.

Can I import data from Excel or Google Sheets?

Yes. Copy your data and paste it directly into the editor. Format: one column for category, one for label, one for value. AECharts sizes the rectangles automatically based on the values.

What export formats are available?

Every chart exports ready to use in PowerPoint or Google Slides, or as an image for reports.

Can I customize the colors?

Yes. Each category gets its own color group, fully customizable. You can also adjust fonts, background color, and label styles to match your brand.

What is a treemap used for?

Treemaps are best for showing proportions within a hierarchy, budget allocation, revenue breakdown, portfolio composition, or file system sizes. They let you see both the total and the parts in a single view.

What is the difference between a treemap and a pie chart?

Pie charts show one level of categories as slices. Treemaps show two levels, categories grouped into colored regions, with individual items as rectangles inside. Treemaps scale better for more categories and give a clearer sense of relative size across many items at once.

Do I need design skills?

No. Templates are professionally designed. Paste your data and adjust colors if needed. Most users create their first treemap in under a minute.

Is there a free plan?

Yes. AECharts is free to start, exports on the free plan include a watermark. The paid plan removes it, starting at $12/month billed annually. No credit card required to start.

Can I use a treemap in a presentation?

Yes. Charts export ready to drop directly into PowerPoint and Google Slides. Treemaps work well as standalone visuals in budget reviews, board decks, and investor updates where you need to show a large breakdown at a glance.

When to Use a Treemap

Treemaps work best when you have many items across a few groups and want to show both the group totals and the individual item sizes at the same time.

Budget Breakdown: Show department budgets and their line items. The rectangle size makes overspend or underspend immediately obvious without a table.
Revenue by Segment: Group revenue by region or business unit, with individual products or accounts inside. Lets leadership see the full picture in one view.
Portfolio Composition: Show asset allocation by category (equities, bonds, alternatives) and individual holdings. Proportions are instantly readable.
Market Share by Sector: Visualize industry sectors and the companies within them sized by market cap or revenue. Works well in investor presentations.
Product Sales Mix: Group products by category and size them by units sold or revenue. Spots top performers and underperformers at a glance.
Expense Breakdown: Show where money is going across departments and line items. More scannable than a table in a board deck or QBR.

Treemap vs Pie Chart vs Bar Chart

Each chart type has a sweet spot. Here's how to choose.

Treemap

Best for: Many items across a few groups where size conveys meaning.
Strength: Shows hierarchy and proportion in a single view, no need for two separate charts.
Use when: Budget reviews, portfolio breakdowns, revenue by product line.

Pie Chart

Best for: 3–6 top-level categories with no sub-items.
Strength: Familiar and compact, everyone knows how to read a pie chart.
Use when: Simple splits with few categories and no drill-down needed.

Bar Chart

Best for: Comparing exact values across many categories.
Strength: Precise, bar length is easier to compare than rectangle area.
Use when: Ranking items or showing changes over time.

AECharts supports all three. Switch between chart types to find the right format for your data.
