This example demonstrates how VizHub integrates D3.js with modern ES6 modules to display a simple text message. The code imports the `select` function from D3 and a custom `message` string from a local module, then renders it inside a styled HTML div. It loads D3 v5 from UNPKG and uses a regular expression and a constant variable to illustrate basic JavaScript syntax. The visualization does not use any data or charting, but highlights the project’s foundational workflow of combining external libraries, local modules, and CSS for a minimal interactive setup.
