CodeAtlas is a tool designed to visualize code dependencies and structures in an interactive and dynamic map. It allows developers to gain insights into code relationships and hierarchies, which can facilitate better maintenance and refactoring efforts. By representing code in a visual graph, CodeAtlas makes it easier to navigate complex codebases, identify areas that require optimization, and enhance overall code understanding. It is particularly useful for large projects where understanding the interdependencies between different modules and components can be challenging.
