Northwind Atlas: A topographic contour map in layered sage greens with one highlighted route line and small coordinate ticks around the edge.

Brief

The grid operator publishes everything and explains nothing. The foundation wanted forty datasets to read as one place.

Idea

A single terrain: height is demand, contour is congestion, colour is carbon. You read it the way you read a hillside.

Build

Twenty weeks with researchers, two engineers and a design system that treats every chart as a map layer.

Launch

It shipped with full keyboard and screen-reader support, and every layer has a plain-language caption.

After

Journalists and regulators began linking to single maps instead of PDFs. It is now the first thing a new analyst is shown.
