This example demonstrates a minimal setup for using D3 within a React project. It logs two arrays to the console: one generated by a custom `simulatedRange` function that manually builds an array of numbers, and another produced by D3's `range(10)` utility. The visualization itself is a bare HTML page with no visual output, highlighting the console-based comparison between a hand-rolled loop and D3's built-in `range` API from the `d3` library.
