Code visualization tools transform code structure into visual formats, helping developers understand, debug, and optimize code more easily. These tools improve readability, reveal dependencies, and enhance collaboration, especially in complex software projects. Here are some useful tools that I frequently use:

• Code2flow generates call graphs for dynamic programming language. Code2flow supports Python, JavaScript, Ruby, and PHP.

• xdot.py is an interactive viewer for graphs written in Graphviz's dot language.

• Visual Studio - Analyze and model your architecture.

• VS Codemap quickly see how your program code fits together without reading through files and lines of code.

• VS dependency diagrams visualize your software system's high-level, logical architecture.
