This example displays metadata about a COVID-19 dataset, reporting its size in kilobytes, row count, and column count as plain text on a page with a coronavirus-themed background. It loads the data from a remote CSV file using `d3.csv`, formats the content with `d3.csvFormat`, and calculates the byte length of the formatted string. The page uses D3 v7 to fetch and process the data, then updates a DOM element’s text content to present the summary.
