This example displays summary statistics for the Top 100 Songs of 2018 dataset, showing the file size in kilobytes, row count, and column count. It loads the CSV data using `d3.csv` and formats the summary with `d3.csvFormat` to measure the byte size of the data. The code also includes commented-out alternatives using `fetch` with async/await and a promise-chain "pyramid of doom" approach, demonstrating different methods for loading and parsing CSV data in D3 v5.
