This visualization maps New York census tracts, using the intensity of orange to represent the population identifying as Black or African American, from 2018 American Community Survey data. It displays tract polygons rendered with `d3.geoPath` in an SVG, colored by a sequential scale using `scaleSequential` and `interpolateOranges`. The code loads TopoJSON geometry and ACS data via `Promise.all`, then maps each tract to its demographic values, with hover highlighting and zoom support via D3’s zoom behavior.

AI-generated description

An intermediate state on the way towards trying to visualize multidimensional data for census tracts. The more orange it is, the more black people there are.
