This example displays a simple text message, "Hello VizHub!", centered on the page with large font styling. It demonstrates a minimal D3.js setup within the VizHub environment, using the `select()` API from D3 to target the HTML element and set its text content. The visualization relies on an external ES6 module to supply the message string, and the page structure is defined in `index.html`. The rendering approach is straightforward, using basic DOM manipulation rather than complex graphical output.
