A Dependency Graph is a visual representation of the relationships between different components in a system. It shows how various elements depend on one another, making it easier to understand the structure and flow of information. Each node in the graph represents a component, while the edges (or arrows) indicate the dependencies between them. These graphs are commonly used in fields like software development, project management, and data analysis. For example, in software engineering, a dependency graph can illustrate how different modules or libraries, such as Java packages or Python libraries, rely on each other to function correctly.
