This example presents a welcome page for the ICE-5 data visualization, displaying metadata about a dataset of the top 100 actors. The page shows a summary message with the file size in kilobytes, row count, and column count, alongside a static SVG image. It uses D3.js v7, specifically the `d3.csv` method to fetch and parse a CSV file from a GitHub gist, and then leverages `d3.csvFormat` to calculate the data size. The layout is styled with simple HTML and CSS, including a large title and a cyan message container.
