Create cartograms where region sizes reflect your data values, or build choropleth maps with color-coded statistical information.

Flexible Map Formats

Upload your custom geographic data (GeoJSON/Shapefile) or choose from our library.

Custom Data Editing

Export your maps as SVG or JSON files, share via direct links, or embed visualizations in websites with responsive iframe support.

Privacy Options

Use our online service for convenience, or deploy offline via Docker/CLI for complete data privacy. Your choice, your data.
