Let's make a face with D3.js!
This example demonstrates how to create a simple SVG visualization: a red background with a face drawn using D3.js. The code selects the SVG element with `d3.select('svg')` and applies a red background color via `svg.style('background-color', 'red')`. It imports the `select` function from the `d3` module and renders the visualization using SVG, with HTML and CSS for basic page structure and styling.
