ChartsIntensity & Density
Packed Bubble
Display categorical data as circles sized by a measure, arranged using a force-directed simulation. Optionally cluster bubbles by a legend field to reveal group patterns. Ideal for showing relative magnitudes in a visually engaging, non-axis layout.
Examples
When to Use
- Comparing magnitudes across categories without axis context
- Showing market share, population, or budget breakdowns
- Highlighting outliers and the relative scale between items
- Creating an engaging visual for dashboards and presentations

Tips & Best Practices
- Enable "Cluster by Category" to group related bubbles together using force simulation
- Use auto label sizing to scale text proportionally with bubble radius — switch to fixed for uniform labels
- Packed bubbles work best with 5–50 items; beyond that, small bubbles become hard to read
