This example displays basic metadata about the 2015 Seattle house price dataset, showing its size in kilobytes, row count, and column count in large text. It loads a CSV file from a GitHub gist using D3 v5’s `d3.csv` method, which returns a promise, then formats the result with `d3.csvFormat` to calculate the byte size. The code also includes commented-out alternatives using `fetch` with async/await and `d3.csvParse`, illustrating different approaches to loading and parsing CSV data.
