This interactive map of New York City boroughs uses a Mercator projection to display a choropleth where each region’s fill color reflects the length of its name. Hovering over a borough triggers a playful “text art” effect that cycles through random Google Fonts, while clicking zooms into the selected region. Built with D3 v3 and React, the visualization leverages `d3.geo.path` for map rendering, `d3.scale.linear` for color encoding, and animated SVG transitions for the zoom effect.
