This example demonstrates a minimal D3.js setup where a user-defined message is rendered in a large, centered style on a dark background, alongside a second element displaying hardcoded text. The visualization imports the `select` function from D3 and a local ES6 module, `message`, to populate the DOM. It also imports car data from a local JSON file, though only the first car’s origin is referenced. The page uses D3 v5 and custom CSS with the Ubuntu font, showing basic data binding and modular file structure.
