[treemap-basic] Basic Treemap

[MarkusNeusinger]

Description

A treemap displaying hierarchical data as nested rectangles, where each rectangle's area is proportional to its value. Excellent for showing part-to-whole relationships in hierarchical structures, making it easy to spot large and small items at a glance.

Applications

• Disk space usage by folder/file
• Budget allocation by department and project
• Market capitalization by sector and company
• Website traffic by country and city

Data

• category (string) - main category
• subcategory (string) - optional sub-category
• value (numeric) - size of each rectangle
• Size: 5-50 items

Notes

• Use distinct colors for main categories
• Add labels for larger rectangles
• Consider borders between rectangles
• Show hierarchy through nesting or color shading

✅ Spec ID: treemap-basic

Rationale: This is a new basic treemap plot type - no existing treemap specifications found.

Waiting for approved label to merge specification.

treemap-basic: Basic Treemap

Description

A treemap displaying hierarchical data as nested rectangles, where each rectangle's area is proportional to its value. This visualization excels at showing part-to-whole relationships in hierarchical structures, making it easy to spot large and small items at a glance. Treemaps efficiently use screen space to display large amounts of hierarchical data in a compact form.

Applications

• Disk space usage visualization by folder and file size
• Budget allocation breakdown by department and project
• Market capitalization comparison by sector and company
• Website traffic analysis by country and city

Data

• category (string) - main category or parent group
• subcategory (string) - optional sub-category for nested hierarchy
• value (numeric) - size/magnitude determining each rectangle's area
• Size: 5-50 items

Notes

• Use distinct colors for main categories to aid quick identification
• Add labels for larger rectangles; smaller ones may omit labels for clarity
• Include subtle borders between rectangles to show hierarchy boundaries
• Show hierarchy through nesting depth or color shading intensity

Next: Add approved label to merge this specification to main.
