{"version":"1.0","type":"rich","title":"cali covid histo","description":"This histogram visualizes COVID-19 deaths over time across all California counties, aggregated into monthly bins that show the total deceased and missing per month. Built with React and D3 v6, the chart uses `d3.histogram` with `timeMonths` thresholds to bin data, `scaleLinear` and `scaleTime` for axes, and SVG rect elements for bars. The data comes from the JHU CSSE COVID-19 time-series dataset, with each bin summing the daily death totals by county.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1559f7de048c4dadbcd6672d42758ed8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
