This example demonstrates how to build a simple visualization using D3.js within the VizHub framework. It imports the `select` function from D3 to target a div element and sets its text content to a pre-defined message imported from an ES6 module. The page is styled with CSS to center the message and scale the font to 12em. The code loads D3 v5 from UNPKG and shows the interplay between local modules, external libraries, and HTML structure.
