This example illustrates the core concepts of reactive programming using asynchronous data streams, drawing from the original tutorial by André Staltz. The visualization, built with React, shows how streams can be created from user inputs and combined using functional operators like map and filter. The code references RxJS observables to demonstrate the flow of data events over time, with an interactive diagram that maps click events and other stream transformations. The rendering uses React components to display the stream diagrams, highlighting how multiple streams can be merged and filtered to produce new data sequences.
