Medical Cost Data
This example summarizes a medical cost dataset loaded from a CSV file, displaying its size in kilobytes, row count, and column count in a large text element. It uses D3 v5’s `d3.csv` to fetch and parse the data, then `d3.csvFormat` to measure the data size. The code also includes commented-out alternatives using `fetch` with `async/await` and a nested promise chain to illustrate different loading patterns.
