This example demonstrates how to set up a minimal VizHub app that loads D3 from a CDN and uses ES6 modules for local code. It shows a simple webpage with the text "Hello VizHub!" displayed prominently, centered via CSS in a div. The code uses `import { select } from 'd3'` to manipulate the DOM and `import { message } from './myMessage'` to bring in a local string constant. The rendering approach is straightforward text content set with `select('#message').text(message)`, with no data source involved.
