This example displays metadata about DC public schools, presenting the dataset’s size in kilobytes, row count, column count, and column names within a styled HTML page. It uses D3 v7’s `d3.csv` to load a CSV file from a GitHub gist, then processes the parsed data with `d3.csvFormat` and `data.columns` to generate the summary text. The page also includes a button linking to the raw dataset and uses CSS for layout and background styling.
