{"version":"1.0","type":"rich","title":"Fork of Multivariate Choropleth Experiments","description":"This example visualizes multidimensional racial demographic data for New York census tracts, showing the relative populations of White, Black, and Asian residents. It uses a multivariate choropleth approach where each tract’s fill color results from blending three HCL color scales (one per race) via multiplicative alpha blending in `d3.scaleSqrt`, with data from the American Community Survey. The map renders as SVG using `d3.geoPath` and TopoJSON, supports zooming via `d3.zoom`, and includes an ordinal color legend. Hovering reveals exact population counts in a tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2392843f1b8448c2b99b5a11b1dcc3cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
