The Class Relation Visualization plugin offers a structured way to analyze and visualize class relationships within Obsidian. By organizing class files with defined categories like inheritance, composition, and aggregation, users can map out connections and dependencies between classes. The plugin features an interactive class relation view that highlights relationships and displays comments when hovering over a class, making it easier to understand the structure and purpose of each class. This visualization tool is ideal for those working on complex systems, allowing for a clearer perspective of class hierarchies and their interactions.
