{"version":"1.0","type":"rich","title":"Untitled","description":"This interactive visualization links a scatter plot, a symbol map, and a time-series brush to explore worldwide COVID-19 aggregated case data. Users can brush a time range to filter the scatter plot and map, or hover over points to highlight matching elements across all views. The visualization uses D3 v3 with `d3.svg.brush`, `d3.geo.path` with an Albers USA projection, and `d3.tip` for tooltips. Data is loaded from local JSON and CSV files containing confirmed cases, recovered cases, deaths, and increase rate over time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ed490d32992a417ba752b01d6af75299?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
