This example demonstrates a minimal setup for embedding D3.js in an HTML page, rendering a red SVG background alongside static text. The code selects an `svg` element using `d3.select` and applies a background color via `style`. It uses D3 v5 loaded from a CDN, with React listed as the framework, though the visible implementation relies on plain HTML and JavaScript. The visualization serves as a bare-bones starter template rather than a data-driven graphic.
