This example demonstrates how to load and parse CSV data using D3’s `d3.csv` method, displaying the file size, row count, and column count of the dataset. It fetches a remote CSV file containing CSS named colors and formats the results in a large `<pre>` element. The code also includes commented alternatives using `fetch` with `async`/`await` and `d3.csvParse`, as well as a nested promise “pyramid of doom” pattern, showing different ways to handle asynchronous data loading with d3.v5.
