About Bubble Charts
When to Use Bubble Charts
Bubble charts are perfect for displaying three-dimensional data relationships where you need to show X and Y coordinates plus a third variable represented by bubble size. Use them to visualize correlations between multiple metrics like sales performance vs market share vs company size, or to compare products across price, quality, and popularity dimensions. They're ideal for portfolio analysis, competitive positioning, risk assessment, and any scenario where you need to display multi-variable relationships in a single, intuitive visualization.
