This example demonstrates the initial step of working with the breast cancer dataset by loading and parsing it, then displaying basic dataset statistics. The page shows the file size in kilobytes, the total number of rows, and the number of columns. It uses D3 v7’s `d3.csv` to fetch the CSV data from a GitHub gist URL, and `d3.csvFormat` to calculate the raw data size. The resulting metrics are rendered as plain text inside a `<pre>` element, providing a concise overview of the dataset’s structure.
