Understanding Treemaps
What is a Treemap?
A treemap is a hierarchical visualization that uses nested rectangles to represent data. The size of each rectangle represents a quantity, while the hierarchy is shown through the nesting of rectangles within larger rectangles.
When to Use Treemaps
- Visualizing hierarchical data structures
- Comparing proportions across different categories
- Analyzing part-to-whole relationships
- Identifying patterns in nested data
- Showing space utilization or resource allocation
Best Practices
- Limit hierarchy levels to maintain readability
- Use clear color coding when representing additional variables
- Include meaningful labels and values
- Consider the aspect ratio for better visualization
- Provide interactive features for exploring detailed information
