This example draws a simple face using D3.js version 5 within a React framework, rendering to an SVG canvas. It demonstrates basic shape creation by appending a circle element with a fixed radius of 200 pixels, illustrating how D3’s selection and attribute methods control SVG geometry. The code imports `select` and `arc` from the D3 module, though only `select` is actively used to target the existing SVG container. The visualization serves as a minimal starting point for building more complex parametric graphics, relying on D3’s data-driven approach to manipulate SVG primitives.
