This example demonstrates a minimal setup for a VizHub visualization using D3.js v5 and ES6 modules. It loads D3 from a CDN via UNPKG, then uses `select` from the `d3` import to target a `div` with `#message` and set its text content from a local ES6 module. A static message, "Hello VizHub!", is styled with CSS. The code also includes unused variables and a regex, but no dynamic data or rendering is performed.
