This example loads and parses a CSV dataset of U.S. housing sales, displaying a summary of the file size, row count, and column count. It first uses `d3.csv` to parse the remote data, then calculates the number of rows and columns from the parsed objects. A separate `fetch` request retrieves the raw file as a blob to compute its size in kilobytes. The summary updates in the DOM, with an error message shown if loading fails. The data is sourced from a GitHub gist hosted by the author.
