What is AlgoFlow and how does it visualize Java algorithms?

AlgoFlow's a Java Agent using bytecode instrumentation to trace and visualize data structures like arrays, trees, graphs in real-time — rewind, fast-forward, no code changes.

Does AlgoFlow require source code modifications?

Nope. Zero changes — just java -javaagent:algoflow.jar YourApp.

Why use bytecode over AST for Java visualizations?

Bytecode's runtime-agnostic, works on any compiled JAR; AST needs source parsing, fragile to changes.
