{"version":"1.0","type":"rich","title":"US Choropleths Map","description":"This visualization renders a choropleth map of the United States, coloring each state by an ILI percentage value to reveal geographic patterns in flu activity. The map uses a threshold color scale with a legend, and state hover effects highlight individual regions. Built with D3.js v4, the code employs `d3.geoPath` and TopoJSON to draw state boundaries from the `us-10m.v1` dataset, while color values come from a TSV file of state-level rates. A secondary bar chart generated with Vega-Lite displays aggregated ILI totals by week and year.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/37ba9a2ebbb046cbafb3a52c8cf83960?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
