What is codemap?

CodeMap is a Python tool that generates visual diagrams from a Python codebase. You point it at a folder of Python files and it produces interactive charts you can open in a web browser, without needing to configure anything first. It creates four types of visuals. A dependency graph shows which files or modules in a project import from which other files, making it easier to see how the pieces connect. A call tree shows an interactive mind-map of how functions call other functions, starting from a function you name. A call graph traces a chain of function calls from one entry point and can export that chain in a format called Mermaid, which embeds directly into Markdown documents. A heatmap colors the codebase by complexity or line count, letting you see at a glance which files are the most tangled or the longest. The tool runs from a command line. You type a short command, point it at your project directory or a specific file, and it writes an HTML file you can open in any browser. There is also a Python API for developers who want to call these functions from inside their own scripts rather than from the terminal. The complexity measurement uses a standard metric called cyclomatic complexity, which counts the number of independent paths through a piece of code. Higher numbers generally mean harder-to-read code. The line-count metric ignores blank lines and comments. A third metric for commit history is listed in the project structure but noted as not yet implemented. Installation requires cloning the repository and running a standard Python package install command. The project is designed to be extended to other programming languages in the future, though only Python is supported in this version.
