Interactive visualization of a simple Cycle.js application showing data flow between streams, events, and DOM.
Draw Cycle is an interactive visualization tool that animates how a simple Cycle.js application works. It demonstrates reactive programming concepts by showing the flow of data between streams, user events, and DOM updates in real-time, using a counter application as an example.
JavaScript developers learning reactive programming concepts, particularly those exploring Cycle.js or functional reactive programming patterns.
It provides a clear visual understanding of reactive data flows that text explanations and static diagrams cannot match, making complex concepts more accessible through interactive animation.

Animates how DOM events transform into streams and DOM updates in real-time, making abstract reactive programming concepts tangible and easy to follow.
Provides a hands-on demo where users can click buttons to see data flow immediately, reinforcing learning through direct interaction with the visualization.
Displays the actual Cycle.js code alongside Raphael.js diagrams, helping developers visually connect JavaScript syntax with reactive behavior patterns.
Explicitly designed to make complex concepts accessible through visualization, as stated in its philosophy, targeting developers learning functional reactive programming.
Only covers a simple counter application from the Cycle.js docs, lacking demonstrations of advanced patterns like HTTP requests, state management, or real-world use cases.
Built in 2016 with older versions of Cycle.js and Raphael.js, which may not reflect current best practices, library updates, or modern reactive programming trends.
The tool is static; users cannot input their own code, modify the visualization, or extend it to explore different scenarios, restricting its utility to the predefined demo.
The README is brief with no setup instructions, tutorials, or explanatory content beyond the basic example, offering little guidance for deeper learning.
