This example displays a large, centered “Hello VizHub!” message on a dark background using the Ubuntu font. It demonstrates a basic D3.js setup, importing the `select` function from D3 to set the text of an HTML element. The message itself is defined in a separate local ES6 module, `myMessage.js`, while the styling is handled by an external CSS file. The code also defines a `Random` utility class with seed-based random and Gaussian distribution generators, though this is not used in the visualization itself.
