B+ Tree order 4. All data lives in linked leaf nodes. Animate insert, search, and range scan — the killer feature of B+ trees over B-trees.

Ready

Default B+ tree loaded. Internal nodes hold only signpost keys (no real data). All data lives in the linked leaf nodes at the bottom — unlike a B-tree where data can live in any node. Try a range scan to see why leaf links matter.
