How to Use
- 1
Paste your columns
Copy label, x, y, and size columns straight from a spreadsheet — a header row names the axes, and the size column drives each bubble’s area.
- 2
Drag the bubbles
Every bubble moves anywhere on the plane. Tap one for exact X / Y / size inputs, color, or remove.
- 3
Label your bubbles
Click any bubble label on the canvas and type — far-right labels flip left automatically so nothing runs off the plot.
- 4
Add context
Toggle a trend line with a live r² readout, switch to a quadrant map with editable captions, five themes, three sizes.
- 5
Download

Frequently Asked Questions
What does the bubble size represent?
A third variable, on top of the x and y position — typically revenue, headcount, or reach. That is the whole reason to choose a bubble chart over a scatter plot.
How many bubbles work best?
Under about fifteen. Bubble charts trade precision for richness, so once they overlap heavily the comparison stops working and a table would serve better.
Can I move the bubbles?
Yes — drag them to position, which is useful when two points land on top of each other and one label becomes unreadable.
What is the quadrant view for?
Splitting the plot into four labelled zones — effort against impact, reach against cost. It turns a cloud of points into a recommendation, which is why it is the standard format for prioritisation slides.
How do I get my data in?
Paste your columns — label, x, y, and size — straight from a spreadsheet, then label individual bubbles on the chart.
Is bubble area or diameter proportional to the value?
Area. Sizing by diameter exaggerates large values dramatically, which is one of the classic ways a bubble chart misleads.
What is this used for?
Market analysis, risk matrices, competitive landscapes, and project prioritisation — anywhere two axes plus a magnitude tell the story.
