This example displays a summary of a CSV dataset, showing the row count, column count, and file size in kilobytes, followed by the first ten rows as JSON. The page uses D3 v7 via `d3.csv` to load the data and the `select` and `append` methods to render the text into `pre` elements. The data source is a local `data.csv` file containing exam scores, and the styling is minimal with a yellow background and large monospaced text.
