This example demonstrates the basic mechanics of loading and parsing a CSV file with D3.js, displaying the resulting dataset’s size, row count, and column count as large text. The code uses `d3.csv` to fetch the data from a GitHub gist containing CSS named colors, then formats the metrics with `d3.csvFormat`. It also includes commented-out alternative code using the Fetch API and `d3.csvParse` with `async`/`await`, showing an equivalent approach for handling the same data.
