How do software developers understand the code that they write? How do they diagnose and correct problems when they appear? Most of the time they reach for unit tests, debuggers, REPLs, or logs. These tools work but have limitations. Debuggers and REPLs show a single point in time on a single thread. Logs become huge and difficult to comprehend. Unit tests cannot solve problems you didn't predict.
We've heard before that visualizations can help but we're tired of waiting for a future when these tools will be delivered. The solution is to build our own interactive visualizations displaying the algorithms we're developing.
