Day 11 (Minimal): I created a minimalist interactive map visualizing pedestrian crashes in University City, Philadelphia, from 2014 to 2024. This visualization embraces the “less is more” philosophy of minimal design by using a dark basemap with simple red circular markers to represent crash locations, creating a stark and impactful visual that immediately draws attention to areas of pedestrian safety concern.
