{"version":"1.0","type":"rich","title":"Fork of Multivariate Choropleth Live Coded at Outlier","description":"This example visualizes racial demographics across New York census tracts by blending colored transparent layers for white, black, and Asian populations. The map uses D3 v5 with `d3.geoPath` and TopoJSON to render tract polygons, while the `color-blend` library applies multiplicative blending of `scaleSqrt`-mapped opacity values for each racial group. Data comes from the American Community Survey API, fetched as JSON, with darker composite colors indicating higher population densities. The visualization supports interactive zoom via `d3.zoom` and hover logging of tract properties.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/895aebba0323405f89d0d68cf146d458?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
