Hello VizHub
This example demonstrates a minimal D3.js visualization that displays a text message on a styled webpage. The code uses `d3.select` to target a `div` element by its ID and sets its content using a message imported from a local ES6 module. Styling is applied via CSS with a custom font and dark background, while D3 v5 is loaded from a CDN. The visualization serves as a simple introduction to VizHub’s ability to combine modular JavaScript, HTML, and D3 library functions.
