Scatterplot matrix
Compare relationships among several numeric measures in one coordinated grid of scatterplots. Create a private, publication-ready scatterplot matrix directly in your browser without transmitting sensitive rows off-device. Data is processed locally on your hardware with zero server uploads, enabling instant export to SVG, PNG, and Excel data.
Edit the data, then export.
Everything runs in your browser. Your data is not uploaded.
Data
Paste tab-separated data from Excel or edit the cells directly.
Paste or import table data
Paste a header row, or choose a local CSV/TSV file. Files are read in this browser and capped at 500 rows.

SVG, PNG, and Excel exports are generated locally in this browser. PowerPoint export is temporarily unavailable while its dependency path is reviewed for a high-severity image parser advisory.
Multi-Variable Correlation & Flow Mechanics
A scatterplot matrix (SPLOM) displays a grid of pairwise scatterplots for multiple continuous variables. The diagonal cells commonly display single-variable distributions, such as histograms or density curves. By organizing all possible dimension pairs into a single matrix, it provides an immediate visual scan of multivariate relationships, linear and non-linear correlations, and clusters. All rendering and data processing happens entirely locally on your device, guaranteeing that your data is never uploaded to any external servers.
Coordinate & Matrix Data Structure
Format input columns for scatterplot matrix with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.
Sample Observation Matrix
| Sepal length | Sepal width | Petal length | Petal width | Species |
Correlation Traps & Analytical Guidelines
- Ensure sufficient visual distinction for scatterplot matrix marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for scatterplot matrix elements.
- Double-check scale boundaries and zero-anchors before exporting scatterplot matrix presentation artwork.
- Data shape
- Label plus two or more numeric measure columns
- Exports
- SVG, PNG, and Excel data; PowerPoint export is temporarily unavailable pending dependency review.
How it works
You edit a table in this page. The renderer draws an SVG from those rows in your browser, then you can download SVG, PNG, or Excel data. The table is not uploaded to any external processing server.
Frequently asked questions
What is the primary benefit of a scatter plot matrix (SPLOM)?
It allows simultaneous inspection of all pairwise correlations, non-linearities, and clustering patterns in a multivariate dataset in one visual grid.
