This example loads a CSV file containing Kent UK police stop and search records and displays a summary of the dataset’s size and structure. It reports the total file size in kilobytes, the number of data rows, and the number of columns. The code uses D3 v5’s `d3.csv` method to fetch and parse the data, and `d3.csvFormat` to calculate the formatted size, with results written to the page via `textContent`. An alternative approach using `fetch`, `async`/`await`, and `d3.csvParse` is included in comments.
