A tree structure is a hierarchical organization of data where each element is connected to a parent node and possesses one or more child nodes. This kind of structure is often used in computing and data processing, but it can also be found in many other disciplines. Synonyms for tree structure include hierarchical structure, network topology, organizational chart, and family tree. In the context of data analysis, you might also hear terms like decision tree, taxonomic tree, or parse tree. Despite its fairly simple design, tree structures can be incredibly versatile and powerful tools for organizing and navigating complex information.
