This example demonstrates how to create a stylized face using D3.js and SVG, with a simple red background applied to the visualization canvas. The code initializes an SVG element sized at 960 by 500 pixels and uses D3’s selection API to modify its style, specifically setting the background color to red. The HTML page loads D3 v5 from a CDN and includes a basic stylesheet that removes margins and hides overflow. The face itself is implied through the structural setup, though the current code only shows the background styling and SVG container creation without explicit facial features.
