Creating face with D3.js
This example demonstrates a minimal HTML page that uses D3.js v3 within a React framework to create a face visualization. The rendering approach relies on a simple CSS-styled message with a large font size, while the JavaScript layer handles the interactive drawing logic. The code uses D3’s selection and data-binding APIs to construct facial features, though the visible output is a static text greeting. No simulation or geo functions are present; the face is formed through basic SVG or DOM manipulation depending on the script additions.
