This interactive bubble chart displays the number of boba shops across eleven Bay Area cities, with circle size scaled linearly by shop count. Built with D3 v7, it renders as an SVG where users can drag bubbles to reposition them while a force simulation, using `d3.forceSimulation` with center, charge, and collide forces, arranges the circles and prevents overlap. Hovering reveals a tooltip showing each city’s name and shop total, with data loaded from a remote CSV file.
