This example shows a React app that routes between a home page with a date picker and a results page, while also fetching historical Bitcoin price data. The code uses `react-datepicker` and `moment` for date selection, and `axios` to request data from the Cryptocompare API endpoint for BTC prices in USD and EUR. A simple switch statement in `routingSystem` controls which component renders, and clicking a "Data" button triggers the API call to populate the app state. The visualization itself is not implemented in the provided code, as it only handles data fetching and basic navigation.
