{"version":"1.0","type":"rich","title":"A9- World Chloropleth","description":"This choropleth visualizes poverty rates across U.S. counties using a threshold color scale with seven shades of red. It renders county boundaries as SVG paths via `d3.geoPath` and topojson, with each county filled according to its poverty value from a CSV dataset. Interactive tooltips display the county name and poverty figure on mouseover, powered by D3 event handlers. The visualization relies on d3.v6, topojson.v2, and d3-legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a9ee02aa5586495c83b0e7849aeeafaa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
