There is a software dependency hell that many developers will encounter, characterized as a frustrating maze created by conflicting interdependencies between software components. This can be solved using graph visualization tools like KeyLines, which can help developers better understand their project's dependencies. By creating nodes and relationships in a Neo4j database, focusing on three relationship types, developers can visualize the network and gain insights into structure, important nodes, circular dependencies, license compatibility, and new dependency branches. The tool provides features such as graph visualization, shortest paths, and filtering to help users explore and understand their data.
