This example loads a CSV file of CSS named colors and displays a text summary of the dataset’s size, row count, and column count. It uses D3 v5’s `d3.csv` promise-based API to fetch and parse the remote data, then writes the result into a large `<pre>` element. The code also includes commented-out alternatives using `fetch`, `async/await`, and `d3.csvParse` to illustrate different parsing workflows. The visualization is purely textual, highlighting the data loading process rather than graphical rendering.
