{"version":"1.0","type":"rich","title":"US Coronavirus Data","description":"This visualization displays the total number of COVID-19 deaths in the United States as a single large numeric figure, formatted with commas and updated to the latest date present in the dataset. It loads the Johns Hopkins CSSE time-series data via `d3.csv`, extracts the most recent column, and sums all state-level death counts using a `reduce` operation. The result is rendered through D3’s `format` function into a large red text element, with a comment showing an unused filter for California data. The code relies on D3 v6 and standard JavaScript array methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1a429ff0727146c9a84e760ac92f1b18?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
