This example demonstrates the core workflow of a VizHub project, from importing local ES6 modules to rendering content with D3. It uses D3’s `select` function to target a `<div>` element and set its text content to a message exported from a separate `myMessage.js` module. The code also defines a numeric constant and a regular expression, showcasing basic JavaScript syntax alongside D3 integration. The page includes a CSS file that centers the message and enlarges its font size, with D3 loaded via a CDN script tag in the HTML.
