Bubble chart best practices
Design expressive scatter-bubble visuals that remain easy to read.
Scale size carefully
Human perception of area is nonlinear. Use square-root scaling so large bubbles do not overwhelm the chart.
Provide reference guides
Add gridlines or annotations so viewers understand the context for each axis and bubble size.

Frequently asked questions
Answers to popular questions about mapping and exporting bubble charts.
What datasets work best for bubble charts?
Bubble charts shine when you have at least three quantitative fields—X, Y, and size—plus an optional category for color. Marketing pipelines, investment portfolios, and scientific comparisons are popular fits.
How do I control bubble overlap?
Use the size slider to scale bubbles proportionally, enable jitter for similar values, or group categories with filters so important points stay visible.
Can I upload my own data?
Yes. Upload a CSV or paste values to instantly generate a chart that you can customize and export. The tool maps the fields automatically.
What export options are available?
Download a crisp PNG or reuse the Vega-Lite specification to embed the interactive bubble chart in your own applications.
