What is a bubble chart?

A bubble chart is a scatter plot where each point has a third dimension: size. The X and Y axes represent two variables; the bubble's diameter represents a third. This lets you compare three metrics simultaneously in a single chart — useful when a scatter plot alone doesn't capture the full picture.

When should I use a bubble chart?

Use a bubble chart when you have three related numeric variables and you want to compare items across all three. Classic examples: market size (X=growth rate, Y=market share, size=revenue), product portfolio (X=cost, Y=revenue, size=margin), country comparisons (X=GDP, Y=life expectancy, size=population).

How many bubbles can I show?

Five to fifteen bubbles works well. Fewer than five and a table communicates the same information. More than twenty and the chart becomes cluttered — overlapping bubbles obscure the data. Use color categories to add a fourth dimension if needed.

Can I import data from Excel or Google Sheets?

Yes. Copy your data and paste it directly into the editor. Format: one row per bubble with columns for X value, Y value, size value, and optionally a label. AECharts sizes bubbles proportionally to the size value.

What is the difference between a bubble chart and a scatter plot?

A scatter plot shows two variables — X position and Y position. A bubble chart adds a third variable through bubble size. If all your bubbles were the same size, the bubble chart would be identical to a scatter plot. Use a scatter plot when two variables are sufficient; use a bubble chart when size adds meaningful information.

Can I add labels to each bubble?

Yes. Each bubble can display a label — category name, value, or both. Labels can be positioned inside or outside the bubble depending on size. For dense charts, hover tooltips are also available.

Do I need design skills?

No. Templates are professionally designed — paste your data and the chart builds automatically. Most users create their first bubble chart in under two minutes.

Is there a free plan?

Yes. All features are free with unlimited image exports. Video exports at 1080p require a Pro plan starting at $19/month billed annually. No credit card required to start.

Can I use a bubble chart in a presentation?

Yes. The MP4 export drops directly into PowerPoint and Google Slides. Bubble charts are particularly effective in strategic presentations — market maps, portfolio reviews, and competitive analysis slides where you need to convey multiple dimensions at once.

Everything You Need to Create Bubble Charts

Three Dimensions in One

X position, Y position, and bubble size — each maps to a variable. Compare markets, products, or entities across three metrics without needing multiple charts.

Proportional Sizing

Bubbles scale automatically to the size variable. The largest bubble always fits within the chart area without manual adjustment.

Video & Image Export

Export as MP4 at 1080p or as a static image. Works in PowerPoint, Google Slides, LinkedIn, and reports.

Color Groups

Assign different colors to categories or groups, adding a fourth dimension. Useful for showing clusters or segments within the same chart.

Real-time Preview

See every change instantly. What you see in the editor is exactly what exports.

No Design Skills Needed

Templates are professionally designed. Paste your data, adjust colors if needed, and export — most users are done in under two minutes.

When to Use a Bubble Chart

Bubble charts work best when position alone isn't enough — when the size of each data point carries meaningful information.

Market Map

X=growth rate, Y=market share, size=total market value. One slide shows where each segment sits and how large it is relative to others.

Product Portfolio

X=development cost, Y=revenue potential, size=current margin. Surface which products deserve investment and which are consuming resources disproportionately.

Competitive Analysis

X=price, Y=customer satisfaction, size=market share. Spot underserved positions and see where competitors cluster.

Country or Regional Comparison

X=GDP per capita, Y=growth rate, size=population. The classic Hans Rosling chart — dense information in a format that's immediately readable.

Employee or Team Data

X=tenure, Y=performance score, size=team size. Show distribution across the organization without a table of numbers.

Risk vs. Return

X=expected return, Y=risk level, size=allocation. Portfolio managers use this to show how assets compare and where concentration lies.

Bubble Chart vs Scatter Plot: Which Should You Use?

Both show relationships between two variables — but bubbles add a third.

Bubble Chart

Best for: Three-variable comparisons where size carries meaning — market maps, portfolio analysis, resource allocation.

Strength: Encodes more information per data point. Audiences immediately see which items are largest without reading a table.

Use when: You have a meaningful size variable that isn't implied by X or Y position.

Scatter Plot

Best for: Two-variable relationships — correlations, distributions, clusters.

Strength: Cleaner and easier to read when the data doesn't have a meaningful size dimension.

Use when: Position alone tells the story — regression analysis, performance outliers, quality control.

AECharts supports both. Use a scatter plot when two variables are enough; use a bubble chart when size adds real information.
