This example demonstrates how VizHub supports ES6 modules and D3.js imports. The code uses `import { select } from 'd3'` to select a div element and set its text content, while a local module `myMessage.js` exports a string value. The page renders a large centered message using CSS from `styles.css`, and D3 is loaded via UNPKG. The example shows basic DOM manipulation with D3’s `select` function and modular JavaScript organization.
