Fork of Multivariate Choropleth Live Coded at Outlier
This fork of a multivariate choropleth live-coded at Outlier maps New York census tracts, blending colored layers to visualize population counts across racial groups. Green, orange, and magenta fills represent white, Black, and Asian residents respectively, with each color’s intensity scaled by a d3.scaleSqrt. The code loads TopoJSON tract boundaries and American Community Survey data via d3.json, then composites the three semi-transparent scales using the color-blend library’s multiply operation. d3.geoPath renders the SVG paths, while d3.zoom enables panning and zooming over the dark canvas.
