{"version":"1.0","type":"rich","title":"Edmonton2019FederalPolling","description":"This visualization maps racial demographics across New York census tracts, blending white, Black, and Asian population counts into a single composite color per tract. Each race’s count is encoded using a square-root scale, with three HCL colors of equal saturation and luminance, then multiplicatively blended to produce the final fill. The map renders as SVG using `d3.geoPath` and TopoJSON, with a shoreline clip-path, hover highlighting, and zoom via `d3.zoom`. Data comes from the American Community Survey API, with a color legend generated by the custom `colorLegend` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/61d61c681e76414aa5bc3bb68653ad7a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
