This example demonstrates how to render a simple text message using D3.js within the VizHub environment. It imports the `select` function from D3 v5 and uses it to set the text content of a `div` element. The message itself is stored in a separate ES6 module named `myMessage.js`, which exports a string constant. The page loads from an `index.html` file that references the D3 library, stylesheets, and bundled JavaScript, with a dark blue background and large centered text.
