This example displays a static list of car prices, including make, model, year, and price, from a hardcoded JSON array in `cars.js`. The page renders the text “Hello world” into an `<h1>` element, which is the only visible output. The code uses `document.getElementById` to set the text content, and imports data via `export` and `import` statements in React. The visualization does not yet chart or graph the data; it merely loads the dataset and displays a placeholder message.
