Hazel Zhang Maps & data
About

I make maps and data legible — usually about cities, climate, and the way people move through both.

Independent cartographer and data designer. Sometimes the output is an interactive map, sometimes a dashboard, sometimes a print you can hold.

Approach

Every project starts with a question the existing maps can't answer, and a dataset that has to be built by hand. I care about ground truth — nothing gets drawn until it's been checked against the world it claims to describe.

The finished piece should read at a glance and reward a second look. No decoration that isn't doing work.
