Hello VizHub
This example demonstrates a minimal D3.js setup that displays a single text message, "Hello VizHub!", centered on a dark background. The code uses D3’s `select` function to target a div element and update its content with a string imported from a separate ES6 module. Styling relies on the Ubuntu webfont and CSS for color and layout. It serves as a basic template for integrating D3 with modular JavaScript and external stylesheets.
