{"version":"1.0","type":"rich","title":"USA cases per million","description":"This visualization displays COVID-19 deaths per million in the United States over time as a date histogram, with each bar colored using a sequential blue scale to encode magnitude. The data comes from a CSV file loaded via `d3.csv`, and the chart uses `d3.bin` with `timeMonths` thresholds to aggregate cases into monthly bins, `d3.sum` to calculate totals, and `d3.scaleTime`/`d3.scaleLinear` for axes. React manages hover interactions, showing a value label above the selected bar.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/17740baa0b714256b97ce1922f6f08fb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
