This example displays a simple HTML list of three used cars with model years, names, and prices, styled with a large monospace font via a linked stylesheet. It demonstrates a basic D3 version 7 setup by importing the `select` function and using it to overwrite the page body text with a greeting, although this behavior does not affect the visible car list. The code includes a CSS rule that sets the font size and family, and references a YouTube tutorial in the README, but shows no data binding, scales, or visual chart generation.
