Fork of Hello VizHub
This example demonstrates how VizHub loads D3 from a CDN and uses ES6 modules to display a simple text message. It shows the basic setup of an HTML page with D3 v5, where the `select` function targets the `#message` div and sets its text content. The message string is imported from a local `myMessage.js` module, and the layout is styled with centered, large font text via `styles.css`.
