This example demonstrates the basic syntax and modular workflow of VizHub, showing how to combine D3.js with local ES6 modules to produce a simple text output. The code imports the `select` function from D3 and a `message` string from a local module, then uses `select('#message').text()` to render "Hello VizHub!" in the browser. D3 v5 loads via UNPKG, and styling comes from a CSS file.
