{"version":"1.0","type":"rich","title":"Bivariate Choropleth","description":"This bivariate choropleth shows the racial distribution of New York census tracts, blending green for white population and orange for Black population using a color-mixing technique from `colorBlend.normal`. The map uses `d3.geoPath` to render topological features and `d3.scaleLinear` for each variable’s color mapping. Data is sourced from the American Community Survey (ACS) API, and the visualization includes zooming interactions via `d3.zoom` and SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a239a4e81b847fda1273b18f0087e2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
