This example demonstrates asynchronous data loading and report generation in a browser. It shows a loading message that updates to a formatted text report after a two-second delay, simulating a network request. The code uses JavaScript ES6 modules with `import`/`export` syntax, a custom `Promise` wrapper around `setTimeout` to fetch car data, and dynamic string construction. It highlights how VizHub loads D3 via UNPKG, though the visible workflow relies on local module functions like `getCars`, `formatCar`, and `generateReport` to process and display car prices.
