This example visualizes a simple face made entirely of SVG shapes, drawn on a red background using D3.js. The code selects the SVG element with `d3.select` and applies a red background style, while CSS classes define green lines and rounded path strokes. It demonstrates basic D3 v5 setup within a React framework, using an empty SVG canvas sized 960 by 500 pixels. The visualization shows how minimal D3 code can structure and style vector graphics, with the face’s details left to be added by the user.
