This example demonstrates a minimalist web page that displays a large, centered, blue "Hello VizHub!" message. It shows how to set up a basic D3.js project within the VizHub environment, including loading D3 via UNPKG and importing both D3 functions and local ES6 modules. The code uses the `select` API from `d3` to target the `#message` div and set its text content. The page's styling, defined in a separate CSS file, changes the message color to gold on hover.
