Introduction

In the ever-evolving landscape of software development, where codebases grow in size and complexity, traditional analysis methods often fall short in providing a comprehensive understanding of a system’s health. This is where graph theory, with its ability to model software as interconnected networks, steps in as a powerful ally.

In this exploration, we’ll delve into the ways graph-based techniques can revolutionize software engineering, tackling challenges in dependency management, modularity, and code quality. We’ll examine how graphs can be used to quantify complexity, identify circular dependencies, assess coupling and cohesion, and even aid in performance optimization and security analysis. We will also discuss the limitations and challenges of graph-based approaches, highlighting the need for continuous innovation in this field.

To showcase the practical application of these concepts, we’ll introduce “Code Health Meter,” a tool I developed to leverage graph-based analysis alongside traditional software metrics. Unlike many existing code analysis tools, Code Health Meter takes a holistic approach, combining the power of graph theory with established metrics to provide a…
