This example demonstrates a scientific data visualization of the ICE-5 dataset, showing summary statistics about the data's size and structure in a text container. It also includes an embedded SVG image and a custom color legend rendered as four simple car graphics, each labeled with a specific color name. The visualization uses D3.js v7 to load and parse a remote CSV file via `d3.csv`, then displays the number of rows, columns, and file size in kilobytes. The SVG elements are drawn manually with basic shapes like `rect` and `circle` to illustrate the color palette.
