This example demonstrates how to load and parse CSV data using D3.js. It fetches a CSV file containing COVID cases and employment statistics and displays the file size, row count, and column count in a large text output. The visualization primarily uses `d3.csv` to parse the data, with commented alternatives showing `fetch`, `async`/`await`, and `d3.csvParse`. A commented-out "pyramid of doom" pattern using nested `fetch` and `response.text()` is also present.
