This example demonstrates how to load and inspect a remote CSV dataset using D3. It fetches a tidy version of the Anscombe’s quartet from a GitHub gist and displays three summary metrics in large text: the file size in kilobytes, the number of rows, and the number of columns. The code uses `d3.csv` to asynchronously parse the data, `d3.csvFormat` to calculate the raw size, and the `data.length` and `data.columns.length` properties to report the dataset’s dimensions.
