This example displays basic statistics about a COVID-19 deaths time-series dataset. The visualization reports the file size in kilobytes, the number of data rows, and the number of data columns in large text. It loads the global death records from the CSSE at Johns Hopkins repository using the `d3.csv` method to fetch and parse the remote CSV file. The code then uses `d3.csvFormat` to measure the payload size and accesses the resulting data array and its `columns` property.
