This example displays a blank, full-viewport SVG scene with a solid red background, rendered through a React application. The visualization demonstrates basic D3.js v5 setup, using `select` to grab the SVG element and applying the background color via D3’s style method. The SVG is sized 960 by 500 pixels, with CSS resetting margins and hiding overflow. The code imports only the `select` function from D3, showing a minimal integration of the library into a React-based workflow, with the SVG markup defined directly in the HTML.
