This example demonstrates how to set up a minimal VizHub project using D3.js and ES6 modules. It renders a static SVG circle while displaying the text “Hello VizHub!” in a separate div element. The code imports the `select` function from D3 via UNPKG, as well as a local `message` constant from an external module, showing modular code organization. The SVG is defined directly in the HTML, with styling controlled by a linked stylesheet.
