A Visual Journey Through Async Rust

- The author prefers visual and experimental learning to understand async execution.
- A sine wave is used to visualize the passing of time in async operations.
- Two futures are created to compute sine values concurrently, demonstrating concurrency vs. parallelism.
- CPU-intensive tasks can block the async executor, affecting other concurrent futures.
- Spawning new Tokio tasks allows for better utilization of multiple CPU cores.
- Using `spawn_blocking` for CPU-heavy tasks can improve performance by utilizing a dedicated thread pool.
- Visualizations show how tasks are juggled between threads and the impact of CPU-bound operations.
- The demo code includes Python plotting scripts to visualize the async operations.
