This example demonstrates basic VizHub functionality by displaying a message in the center of the page. It shows how to load D3 from a CDN via UNPKG and use the `import` statement to access both D3 APIs and local ES6 modules. The code imports `select` from `d3` and a `message` string from a local file, then sets the text content of an HTML div element. Styling is applied through an external CSS file to control font size and alignment.
