{"version":"1.0","type":"rich","title":"Choropleth map in D3","description":"This choropleth map visualizes 2023 US unemployment rates by state, coloring each state with a sequential scale from the minimum to maximum unemployment values. Hovering over a state reveals a tooltip with its name and unemployment figure. Built with D3.js, it loads unemployment CSV data and US state TopoJSON boundaries, then projects the states using `d3.geoAlbersUsa` and renders them as SVG paths via `d3.geoPath`. The map joins the CSV data to the geometry using a state name-to-FIPS code mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ffcf82644e3e4cdcb918684ae4433a9d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
