Answer
$graphLookup performs recursive lookups, useful for hierarchical structures like org charts or categories.
Quick Answer
$graphLookup performs recursive lookups to traverse graph or tree-like data. Given a starting document, it recursively fetches documents connected via a specified field. Use for: org charts, friend-of-friend networks, category hierarchies, file system trees. More efficient than multiple application-side queries for graph traversal. Set maxDepth to limit recursion.
