## Resource

In this episode, I sit down with Bill Rankin, historian of science at Yale and author of Radical Cartography, to unpack what maps really do beyond simply showing data. We talk about why mapping is an act of representation with real consequences, how common techniques like choropleths and cartograms shape what we see—and what we miss—and why there's no single "correct" way to visualize the world. Bill shares how his background in architecture influences his approach to mapping as drawing and world-making, not coding or dashboards. We also dig into static versus interactive maps, accessibility, and why starting with questions—not tools—leads to better visualizations. It's a thoughtful conversation about intention, trade-offs, and responsibility in data visualization.
