This example displays a hardcoded JSON array of four car objects with model, price, and color fields, parsed by `JSON.parse` and exported from a separate module. The main script imports the data and writes the static string "Hello World" into a `<pre>` element using the DOM API. Built with D3 v5 and React, the visualization primarily demonstrates data setup and basic DOM manipulation, though the included face-drawing capabilities are not actively invoked in the current code.
