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.
