This example demonstrates a minimal D3.js application that displays the text “Hello VizHub!” in the center of the page. It uses the `select` function from D3 v5 to target a `#message` div and set its content from a local ES6 module. The code also imports the D3 library via UNPKG and separates the message string into a modular `myMessage.js` file, showing basic module import patterns and styling with CSS.
