{"version":"1.0","type":"rich","title":"Chloropleth Map","description":"This choropleth map displays the 2022 unemployment rate for each U.S. state, with a blue sequential color scale indicating higher rates. It uses d3.geoPath with a d3.geoMercator projection to render state boundaries from a TopoJSON file, while a threshold scale maps unemployment percentages to d3.schemeBlues. Hovering over a state changes its fill to red via CSS. Data comes from a CSV file joined to state names, and tooltips show the exact rate per state.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4aecc57fc02e42d395bd784240145daf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
