{"version":"1.0","type":"rich","title":"6 weeks Covid-19 cases of 3 Counties, Ohio","description":"This visualization presents six weeks of daily COVID-19 case counts for three Ohio counties—Butler, Hamilton, and Montgomery—as separate heatmaps stacked vertically. Each chart maps week on the y-axis and day of week on the x-axis, with cell color intensity reflecting case volume via a blue sequential scale. Hovering reveals the exact date and case number. The code uses D3.js v6 to load CSV data, build band scales, and render SVG rectangles with tooltip interactions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a3f531dde8e345078c056847ba4e5613?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
