{"version":"1.0","type":"rich","title":"Final Project","description":"This interactive choropleth map shows cumulative COVID-19 cases per U.S. state as of September 2021, with darker fills representing higher case counts. Clicking a state displays a tooltip with its name, total cases, and total deaths. The visualization loads county-level data from a CSV via `d3.csv`, aggregates it by state using `d3.rollup`, and renders SVG paths from TopoJSON using `d3.geoPath`. Color opacity is scaled proportionally to each state’s case total, with a bivariate legend circle appended on click.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/23a8005ee7a2409c8cd848b9f443679a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
