{"version":"1.0","type":"rich","title":"Edmonton2019FederalPollingRiverbend","description":"This visualization displays the racial demographics of Edmonton’s federal polling district Riverbend using census tract boundaries. Each polygon’s fill blends three HCL color-space scales—one each for White, Black, and Asian populations—using a square root scale for value encoding. The map is rendered with D3 v6’s `geoPath` and topojson, with hover strokes highlighting tract boundaries. Data is sourced from the 2018 ACS API, and a legend labels the three color categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e603ef3a0ff3475d94f300bbbdfaa2bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
