About Graph Data Modeling Languages

Unlike relational databases, there is no single standardized ERD equivalent for graph databases.
However, several visual and conceptual tools exist:

Neo4j Graph Data Modeler (in Neo4j Workspace)
A built-in visual tool that lets you draw nodes, relationships, and properties interactively.
Arrows.app (https://arrows.app)
A free online diagramming tool maintained by Neo4j engineers. It uses simple node–relationship diagrams that match Cypher syntax — perfect for quickly sketching graph structures.
GraphQL Schema for Graph Databases
Some teams model graphs using GraphQL schemas (especially when using Neo4j GraphQL). It can serve as a semi-formal description of the graph’s domain.

In practice, graph data modeling is more about describing relationships and traversal paths than about strict cardinality and normalization rules.
You usually start from questions you want to ask (“who is connected to whom, through what?”) and model nodes and relationships accordingly.
