Hello D3
This minimal example presents a blank page that centers a large, invisible title placeholder, with all output directed to the browser console. It demonstrates the foundational pairing of D3.js version 6 with React, loading the library via a `<script>` tag from a CDN. The code logs a JavaScript greeting and includes a commented-out `d3.select` call, highlighting the basic setup for a new D3 project while leaving the actual visualization steps for further development.
