This example prints a summary of a dataset containing the mass and height of 500 people, along with their gender. It displays the row and column counts, the estimated file size in kilobytes, and the first 100 rows as formatted JSON. The code loads the CSV from a Kaggle-sourced URL using `d3.csv`, then uses `select` and `append` to render the text into `<pre>` elements, with `csvFormat` calculating the data size.
