{"version":"1.0","type":"rich","title":"Multivariate Choropleth Experiments","description":"This example visualizes racial demographics for New York census tracts using a multivariate choropleth. It blends three HCL color constants (white, Black, and Asian) with square root scales, applying a multiplicative color blend to produce composite hues per tract. The map renders via `d3.geoPath` with TopoJSON data, supports zoom interaction, and includes a legend built with `d3.scaleOrdinal`. Data comes from the American Community Survey API, fetched through a gist-hosted JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad3f8d0a56cb4293864154a7c62719d4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
