Hello VizHub
This example demonstrates a simple text-based visualization that displays the message "Hello VizHub!" on a dark, styled webpage. The page uses D3.js v5’s `select` function to target DOM elements, while a separate ES6 module (`myMessage.js`) exports the displayed text. The code also manually sets text content via `document.getElementById`, and applies custom typography and colors through an external stylesheet with the Ubuntu font. The visualization is static, showcasing basic DOM manipulation and module import patterns.
