A C++ tool that generates artistic maps by running Dijkstra's shortest-path algorithm over OpenStreetMap data, rendering the most-used routes as images. It was used to create posters like 'all roads lead to my home' in Paris, the Amazon river network, European railways, and world flight paths.

Use cases

• generate a shortest-path map poster of my city
• visualize road usage from OpenStreetMap data
• draw river or railway networks with Dijkstra's algorithm
• create a 'roads to Rome' style map from my home
• render flight route maps from graph data

When to choose

• you want artistic shortest-path density maps from OSM data
• you need a customizable open-source alternative to Roads to Rome
• you're comfortable building C++ and working with OSM extracts

When to avoid

• you need a maintained production routing engine like OSRM or Graphhopper
• you want a polished GUI or turnkey tool
• you need up-to-date support or a permissive license
