This example displays a simple text summary of a remotely loaded CSV file, showing its size in kilobytes, row count, and column count. The visualization uses D3.js version 5 and the `d3.csv` method to fetch and parse the data from a GitHub gist containing CSS named colors. The code also includes commented-out alternatives using `fetch` with async/await and a nested promise “pyramid of doom” to illustrate different approaches to asynchronous data loading, though only the `d3.csv` path is active.
