This visualization shows 114 HOLC redlining zones in Milwaukee from 1938 as extruded 3D blocks. Each zone is color-coded by its HOLC grade: green for A (Best), blue for B (Still Desirable), yellow for C (Declining), and red for D (Hazardous). D-grade zones are the tallest, representing the lasting damage of discriminatory lending policies. Two zones are ungraded and shown in gray.
