This example demonstrates how to combine D3.js with ES6 modules in a minimal VizHub setup. It uses the D3 `select` function to target a `#message` div and update its text content with a string exported from a local module. The page loads D3 from UNPKG, while the main script imports both D3 utilities and a custom `message` function from a separate JavaScript file. The rendering approach is straightforward DOM manipulation, with a CSS stylesheet controlling the text alignment and size.
