This example demonstrates the basic capabilities of VizHub by displaying the text "Hello VizHub!" prominently in the center of the page. Using D3 v5 loaded via UNPKG, the code imports the `select` function to target the HTML element with the ID `message` and sets its text content. The message itself comes from a local ES6 module, `myMessage.js`, which exports the string constant, and the styling is handled by an external CSS file.
