This example demonstrates a minimal D3.js starter template, rendering an empty SVG element onto a blank page. The visualization serves as a basic foundation, with the page’s body text styled at an extreme font size to showcase the framework’s setup. The code explicitly calls `d3.select('body').append(svg)` to attach an SVG container, relying on the D3 v7 library loaded from the unpkg CDN. No data or visual marks are drawn, making it a pure initiation into D3’s DOM manipulation and rendering structure.
