This example displays metadata about a COVID-19 dataset loaded from a GitHub gist, showing the file size in kilobytes, row count, and column count as plain text. The visualization demonstrates loading D3 v5 via UNPKG, using `d3.csv` to fetch and parse the CSV data, and `d3.csvFormat` to calculate the data’s size. It also illustrates importing from local ES6 modules, though the primary output is a simple text-based summary rather than a graphical chart.
