This example renders a full-screen “Hello VizHub!” message in large, bright Ubuntu type on a dark navy background. The code demonstrates basic D3.js DOM selection using `d3.select` to set the text content of a div, alongside an ES6 module export for the message string. It uses D3 v5, loaded from a CDN, with styling defined in an external CSS file and a minimal HTML skeleton. The visualization’s purpose is purely illustrative, showcasing component separation and library integration.
