This example demonstrates how to begin using D3 version 6 by loading a small JSON dataset of car specifications and displaying the make of the first car in the dataset. The code parses a hardcoded JSON string with `JSON.parse` and uses standard DOM methods to set the text content of an HTML element, applying CSS styling for centered, large text. The page includes a linked YouTube tutorial and loads D3 from the official CDN, but the visualization itself relies solely on native JavaScript and DOM manipulation rather than D3-specific functions.
