Subway Map

Subway Map borrows from one of the most successful information design inventions in history: Harry Beck's 1931 London Underground diagram. Colored lines trace routes between station dots, interchange nodes mark where paths cross, and the entire topology is simplified into horizontal, vertical, and 45-degree angles.

The orange-red accent (#FF5722) serves as the primary route color, with secondary lines in blue, green, and purple. Station dots are uniform circles — filled for major stops, outlined for minor ones. Interchange nodes use concentric rings or crossed-line markers. The background is clean white or pale cream, letting the colored routes dominate.

This style maps naturally onto process flows, learning paths, product roadmaps, organizational charts, and any sequential or branching information. The transit metaphor is universally understood: you are here, these are your possible routes, these are the stops along the way. It transforms abstract workflows into navigable journeys.

Subway Map's genius is topological rather than geographical — it preserves relationships while discarding irrelevant spatial accuracy. Applied to infographics, this means complex multi-path processes can be rendered clearly without the clutter of true-to-scale positioning. The style gives audiences permission to focus on sequence and connection rather than distance and proportion.
