This example demonstrates the basic use of VizHub to create a simple D3.js visualization. It loads D3 version 5.16.0 from a CDN and uses the `select` API to target a `div` element by its ID, setting its displayed text to a message imported from a local ES6 module. The page also applies styling from an external CSS file, centering the large text output. The visualization serves as a minimal template for integrating D3 with modular JavaScript and external libraries.
