This example demonstrates VizHub’s ability to load D3 via UNPKG and use ES6 modules for local code organization. It imports the `select` function from D3 and a custom `message` constant from a local `myMessage.js` module. The code uses `select('#message').text(message)` to set the text of a centered `<div>` styled with CSS. The visualization simply displays “Hello VizHub!” in large type, with no data or animation involved.
