Hello VizHub
This example introduces VizHub’s workflow by rendering a fixed, preformatted message element. It loads D3 from UNPKG and demonstrates ES6 module imports for both the external D3 library and a local `cars.js` module, which exports parsed JSON data. The main `index.js` script sets the text of the message element to “Naon”. The visualization itself is minimal, focusing on the mechanics of module loading and DOM manipulation rather than data-driven graphics.
