This example demonstrates how to load and parse a COVID-19 time-series dataset from the CSSEGISandData GitHub repository. It displays a summary of the loaded data, including its size in kilobytes, row count, and column count, using a large text message. The code relies on D3 v5’s `d3.csv` to fetch the CSV file and `d3.csvFormat` to calculate the data size, then updates the DOM via `textContent`. The visualization is purely a data-loading diagnostic, not a graphical chart.
