FAQ
Bubble Chart Maker questions
- How many columns does a bubble chart need?
- Three numeric columns: X, Y and size. A leading text column is used to name each bubble in the tooltip.
- Is bubble size mapped to area or radius?
- Area. Mapping to radius exaggerates large values because area grows with the square of the radius — area keeps the comparison honest.
- What if my bubbles overlap?
- Bubbles are drawn semi-transparent so overlaps stay readable. If you have hundreds of points, a hexbin plot is usually the better choice.
