This example demonstrates a minimal D3.js setup within VizHub, rendering the text “Hello VizHub!” into a centered message div. It highlights fundamental workflow patterns: loading D3 v5 from UNPKG, importing the `select` function via ES6 modules, and importing a local module (`myMessage.js`) for the message content. The visualization is a simple static text output, with styling applied through an external CSS file. The code illustrates the basic structure for combining CDN-hosted libraries with modular JavaScript.
