This example demonstrates a minimal D3.js setup that renders the text "Hello D3 version 6" in the browser. It uses d3.select to target the body element and set its text content, while the page's CSS styles the text at an oversized 13em font size. The code imports the select function from D3 v7 via npm, and the HTML loads the full D3 library from a CDN bundle. The visualization simply verifies the D3 library is properly installed and executing.
