Scatter Plot Maker: Free XY & Bubble Chart Images
Making a scatter plot image is quick: open the free scatter plot maker, add a row for each point with an X and a Y value, color by group if you like, and download a PNG or SVG. It's the fastest way to show whether two numbers move together, without wrestling with a spreadsheet chart.
What a scatter plot showsWhat a scatter plot shows
A scatter plot puts each point where its two values meet: one on the X axis, one on the Y. Line up a set of them and the shape tells the story. A cloud that drifts up and to the right means the two numbers rise together, a flat blur means they don't, and a stray dot off on its own is an outlier worth a look. The format goes back to John Herschel in the 1830s and it still reads faster than any table.
You reach for one when the relationship between two numbers is the question:
- Correlations: ad spend against revenue, price against rating, hours against output.
- Clusters: customers or results grouped by segment, each group its own color.
- Bubbles: a third value as the dot size, so three numbers share one chart.
You could list the same pairs in a table, but then the reader has to picture the pattern themselves. A scatter draws it for them. Fifty rows of numbers become one shape you read in a second.

Open the scatter plot maker. You add a row for each point and type its X and Y. Add a category and points in the same group share a color, with a legend added for you. Give a point a size and it grows into a bubble. The chart redraws as you go, so you can tune the data until the pattern reads clearly.
There's no account to create and nothing to install. Turn on the trend line for a least-squares fit, caption the axes, and switch to a dark background for slides or social. When it looks right, you download it. You get a clean PNG for docs, or an SVG if you want it sharp at any size. No signup, no watermark, no credit card.
That handles the one-off. If you rebuild the same chart every week or need one per report, keep reading.
Embed it anywhereEmbed it anywhere
A scatter plot from the tool is just an image, which is what makes it easy to place. Drop it into a slide, paste it into an email, or add it to a doc. In markdown or HTML, one line does it:
Static files are fine for a fixed chart. But if your numbers move, you don't want to redraw it by hand. Embed a render URL instead of a saved file and the image regenerates on each load, so the plot reflects the latest points without you reopening anything. Same one-line embed, live data behind it.
Generate at scaleGenerate at scale
When you need more than one chart, the API takes over. A single render call turns your points into a finished image, and you swap the data per request. One design covers every report, every dashboard tile, or every automated email.
Here are the paths, from least to most hands-off:
- API: the API docs walk through a render call with working examples ready to paste.
- Component: the scatter plot works as an API component. Define the points, colors, and sizes as fields, then render whenever. See the scatter component for what's configurable.
- AI agent: an AI agent can build the chart over MCP, so you describe the plot in plain language and it produces the image.
Pick the level that fits. A quick script wants the API, a repeatable design wants the component, and a hands-off workflow hands it to an agent.

For a single chart, the scatter plot maker gets you a PNG or SVG in a minute, free and unwatermarked. To automate it, read the scatter component reference, then wire it up through the API docs or hand it to an AI agent.
The free plan includes 100 renders a month, which is plenty to test the automated path before you scale it. Build the chart that finally makes your correlation obvious to the people reading it.
