This example demonstrates how to load and inspect a movie review dataset using D3 version 7. It fetches a CSV file from a GitHub gist, then displays the dataset's size in kilobytes, row count, and column count within an HTML page. The code uses the `d3.csv` function to fetch and parse the data, then `d3.csvFormat` to calculate its size, and writes the summary to the page via a DOM `textContent` assignment. The visualization is minimal, focusing on metadata rather than graphical representation.
