Local map canvas generator
Skip to the chartLocal map canvas
Explore country-level values with bundled world geometry and no external map tiles or network requests. Create a private, publication-ready local map canvas 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.
Statistical Distribution & Shape
A local map canvas visualizes geospatial data—such as countries, regions, or municipalities—using bundled vector geometry instead of relying on external map tile servers. All mapping boundaries are rendered directly in the browser via SVG or Canvas. Because it processes all data locally with no server uploads, it guarantees complete privacy for sensitive location-based datasets.
Data Requirements & Continuous Variables
Format input columns for local map canvas with explicit headers and numerical measurements. Verify that rows represent discrete nodes or geographic units without unformatted symbol artifacts.
Sample Distribution Data
| District | Density (pop/km2) |
Guidelines for Interpreting Distributions
- Ensure sufficient visual distinction for local map canvas marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for local map canvas elements.
- Double-check scale boundaries and zero-anchors before exporting local map canvas presentation artwork.
- Data shape
- Country name and numeric value 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
Can I use custom GeoJSON files with the local map?
Yes, local TopoJSON and GeoJSON boundary objects can be rendered client-side in the browser.
