This example creates a pink SVG canvas using D3.js v5, accessed via `d3.select('svg')` and styled with a background color. The visualization demonstrates D3's core selection and styling capabilities with the `svg` element, setting up a blank 960x500 pixel drawing area. The code prepares the stage for building a face by manipulating SVG attributes through the D3 API, while the external stylesheet uses CSS to reset page margins and handle overflow. It shows how D3 integrates with HTML, CSS, and SVG to construct a web-based graphics environment.
