Bubble chart best practices

Design expressive scatter-bubble visuals that remain easy to read.

Limit bubble categories

Use color to distinguish a handful of groups. More than six categories can make the legend and chart difficult 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.

How to use the bubble chart maker

Move from spreadsheet to shareable chart in three steps.

Import metrics for X, Y, and size

Upload a CSV or paste data so each column maps to a bubble position or dimension.

Tune encodings and styling

Assign colors, adjust bubble scaling, add labels, and set tooltips to highlight your story.

Export or embed your visualization

Download a high-resolution image or copy the Vega-Lite spec to share interactive charts anywhere.

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.
