This visualization displays the total number of COVID-19 deaths in the United States, aggregated from the latest date in a time-series dataset supplied by the CSSE at Johns Hopkins University. It shows a single large text value that updates dynamically based on the data. The code uses the D3 library (d3.csv) to fetch and parse the CSV file, then applies a reduce function with a sum accumulator to calculate the total. A comma formatter from d3.format displays the result within a pre element.
