This example demonstrates how VizHub supports modular ES6 development with D3 by rendering a simple text message. The page displays “Hello VizHub!” centered in large type using CSS styling. The code imports the `select` function from D3 and a local `message` export from an ES6 module, applying it to a div via `d3.select().text()`. D3 is loaded from UNPKG as a CDN script, while the local JavaScript modules are bundled together.
