This example demonstrates a minimal "Hello World" visualization setup using D3.js v5, displaying a fixed text message in the browser. It shows how to load D3 from a CDN via UNPKG, import local ES6 modules, and apply CSS styling. The code defines a message in both `index.js` and `myMessage.js`, though only the static text is rendered. It uses D3's library import and local module imports to structure the project, serving as a basic template for VizHub development.
