AutarkA modular urban toolkit for data visualization on the web

Load, analyze, and render geospatial data entirely in the browser — no server required.

autk-db

Load and query geospatial data in the browser using DuckDB-WASM. Supports OpenStreetMap, GeoJSON, CSV, and more.

Render 2D and 3D maps on a canvas using WebGPU. Handles large datasets without a tile server.

Run custom computations across GeoJSON features in parallel on the GPU using WGSL shaders.

Build interactive D3 charts that link directly to map selections for coordinated views.

Case Studies

End-to-end urban visual analytics applications built with Autark. These cases combine multiple modules into full interactive experiences.

Explore Manhattan in 3D with neighborhoods, thematic layers, parallel coordinates, and linked tables powered by Autark.

Explore the Boston street network and electric vehicle charging stations in an interactive map.

Examples

Interactive examples showcasing the core capabilities of Autark. Each example runs entirely in the browser.

A minimal example that loads a projected GeoJSON file of Manhattan neighborhoods and renders it directly in Autark.

A browser-side spatial join example that counts noise points inside Manhattan neighborhoods and visualizes the result as a thematic map.

A live example that queries OpenStreetMap through Overpass API and renders a multi-layer 3D scene of Manhattan directly in the browser.

This example is currently under development.

A coordinated multiple views example linking an interactive map with a custom bar chart. Selecting elements in one view highlights them in the other.
