Hello VizHub
This example demonstrates the fundamental capability of VizHub: rendering a personalized message directly in the browser. It displays the text "Hello!" prominently against a dark blue background with large, centered Ubuntu typography. The code imports the D3.js `select` function to target a specific HTML element and set its content. It also showcases ES6 module usage by importing the message string from a separate `myMessage.js` file, illustrating how VizHub projects can organize code into reusable components.
