Hello VizHub!
A "Hello VizHub!" example shows a single line of text, "Hello VizHub!", centered against a dark charcoal background in a large, light-colored Ubuntu font. It demonstrates a minimal D3.js project setup. The visualization renders a static `<div>` element using D3's `select` function to target the element by ID and set its text content. It imports that text from a separate ES6 module and relies on D3 v5 as the sole external library.
