How do I show capacity per corridor?

Vary the line thickness in proportion to capacity (e.g., GW for power, vehicles/day for transport) and add a thickness legend in the corner.

Cross-Regional Corridor / Network Map

Country outline with multi-stage build-out of a network corridor across regions.

When to use this prompt

For policy briefs, infrastructure plans, energy / transport corridor proposals.

The prompt

A horizontal three-stage map graphic showing a cross-regional corridor evolving across stages.

Layout: three side-by-side simplified country outlines (same country across all panels), each panel labeled at the top: "Stage 1: Initial Corridor", "Stage 2: Expanding Network", "Stage 3: Integrated National Network".

Stage 1 — A single corridor connecting an origin point (subtle marker on a coast) to a primary inland hub. Few nodes (4-6) with thin connecting lines.

Stage 2 — More nodes (15-20) and additional corridors branching from the original spine into adjacent regions. Some nodes are highlighted as "interchange hubs".

Stage 3 — Dense network with nodes spanning the full country and corridors meshed across regions. Major hubs labeled with city names.

Use a consistent color for the corridor edges across stages. Use small dot markers for nodes and slightly larger ringed markers for hubs. Country borders rendered as thin neutral lines.

Style: clean policy / infrastructure infographic, restrained palette (slate country, teal corridors, amber hubs), white background, sans-serif labels. Suitable for government concept papers and energy / transport plans.

Variations

Add cross-border extension

Add a fourth stage showing extension into a neighbouring country (faded outline) with cross-border interchange points highlighted.

Tips

Use the same country outline across stages. Different shapes destroy the build-up narrative.
Tie color to corridor type, not stage. Stage is communicated by panel order.
Label only major hubs. Labeling every node turns the map into a list.
