Fork of D3 Starter
✓ Published0🌍 Public
This fork of D3 Starter uses SVG rendering to display a choropleth map of US counties with bubble overlays sized by population. The visualization loads TopoJSON geographic data and renders county boundaries, internal state lines, and semi-transparent red circles at each county centroid where circle radius is scaled by the square root of population using `d3.scale.sqrt`. Interactive tooltips on hover reveal county names and population values. The code uses `d3.geo.path` for geographic projection and `topojson.mesh` for state borders, with `d3.select`, `.data()`, `.enter()`, and transition methods for dynamic styling. A YouTube tutorial link is embedded in the README.
