Treemap

This documentation pertains to the unsupported version of NeoDash, as part of Neo4j Labs. For users of the supported NeoDash offering, refer to NeoDash commercial.

Advanced Visualization

A treemap chart will render hierarchical data in a nested rectangle layout. It takes two fields:

Path: a list of strings. This represents the hierarchy (from highest to lowest level).
Value: a number that matches the size of the element at the lowest level. Sizes of non-leaf levels are determined from the sum of their children.

Examples

Basic Treemap

MATCH path=(:Company{name:'NeoDash'})-[:HAS_DEPARTMENT*]->(:Department)
WITH nodes(path) as no
WITH no, last(no) as leaf
WITH  [n IN no[..-1] | n.name] AS result, sum(leaf.employees) as val
RETURN result, val
