This example demonstrates loading and parsing a CSV dataset using D3 v7, displaying summary statistics about the data in a styled HTML page. It shows how to fetch external data with `d3.csv` and present metadata such as file size, row count, and column count in a `<pre>` element. The visualization also embeds an SVG illustration of a simple house, rendered with basic shapes like rectangles and a polygon. The code uses D3's promise-based loading API and dynamically updates the DOM via `textContent`, while the accompanying CSS styles the header and metadata block.
