This example displays summary statistics for Boston crime data from 2020, showing the dataset’s size in kilobytes, row count, and column count in large text. It loads the CSV from a GitHub gist using `d3.csv`, then calculates the file size by measuring the formatted CSV string length and divides it by 1024. The code also includes commented-out alternatives using `fetch`, `async`/`await`, and `d3.csvParse`, demonstrating different approaches to asynchronous data loading. The visualization is minimal, rendering the final message into a `<pre>` element using standard DOM text assignment.
