Bivariate choropleth
Compare two country-level measures at once with a two-dimensional color scale. Create a private, publication-ready bivariate choropleth 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.

Multi-Variable Correlation & Flow Mechanics
A bivariate choropleth map visualizes the spatial relationship between two distinct quantitative variables simultaneously on a single geographic layout. By using a 2D color matrix (typically a 3x3 blended color grid), it assigns a unique blended color to each geographic region based on its values for both variables. This helps identify regional correlations and spatial clusters without needing side-by-side maps. All data processing and geographic rendering occur entirely on your local machine, guaranteeing complete data privacy with no server uploads.
Coordinate & Matrix Data Structure
Format input columns for bivariate choropleth with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.
Sample Observation Matrix
| Region | Median income | Graduation rate |
Correlation Traps & Analytical Guidelines
- Ensure sufficient visual distinction for bivariate choropleth marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for bivariate choropleth elements.
- Double-check scale boundaries and zero-anchors before exporting bivariate choropleth presentation artwork.
- Data shape
- Country name plus two 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
How do you read a 2D bivariate choropleth legend?
One axis represents Variable 1 (e.g. blue), the other represents Variable 2 (e.g. pink), and the top-right corner represents regions high in both (blended dark purple).
