{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This example shows a choropleth map of US states with an interactive slider that filters states by population, highlighting those above a threshold in steelblue while leaving others lightgray. The map uses D3 v7’s `d3.geoAlbersUsa` projection and `d3.geoPath` to render TopoJSON state boundaries from `us-10m.v1.json`. Population data loads from a local CSV file, and the slider triggers a filter function that updates the fill colors. The visualization also includes a legend showing the current filter percentage.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/50dd92f48a1f4b3b82fcc93613c2b120?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
