This example shows a simple red-background SVG canvas featuring a smiley face with animated eyebrows. The visualization demonstrates fundamental DOM manipulation using D3.js v5, specifically through the `d3.select` API to target the SVG element and apply styling. The animation is driven by manipulating the eyebrow elements' positions over time, though the precise transformation logic resides in the bundled JavaScript file. The final output is rendered as an SVG graphic, with the container set to hide overflow and remove default page margins via external CSS.
