工作报告、广告与作业中适合叶子多且有层级的部分-整体。若需要精确比较相近大小时，换一种形式。
Work
- 工作 1 — PowerPoint weekly: 矩形树图 for 叶子多且有层级的部分-整体.
- 工作 2 — One 矩形树图 on a quarterly bridge or KPI tile — not four.
- 工作 3 — Build in Excel 或 Google 表格, export SVG/PDF rather than a screenshot.
Ads
- 广告 1 — 微信、抖音与展示广告: one number, one shape, one arrow.
- 广告 2 — Keep callouts inside safe zones. No type in cropped corners.
- 广告 3 — If 矩形树图 will not fit a banner, keep the number and show the chart on the landing page.
School
- 学校 1 — 实验报告与展板: does 矩形树图 answer 评分标准?
- 学校 2 — Axis names, units, a source line. Markers read them.
- 学校 3 — Start with a mind map if you must; submit a figure that reads like 矩形树图.
Steps
- 步骤 1 — Write the claim in one sentence.
- 步骤 2 — Check that 矩形树图 fits the claim. If not, switch.需要精确比较相近大小时
- 步骤 3 — Draw it flat in Excel 或 Google 表格 or PowerPoint.
- 步骤 4 — Direct labels, faint grid, claim-title.
- 步骤 5 — Check greyscale and a color-blind simulator.
- 步骤 6 — Add source, period, units; export SVG/PDF.
