toro4n docs

toro4n is an online tool for drawing graph data models for Neo4j and other property graph databases. These pages explain each part of it; the app itself needs no sign-in and nothing to install.

Drawing

• Nodes and relationships – labels, relationship types, direction, captions, circles and cards.
• Properties – key, Neo4j type, and example; unique and required; pasting a whole block.
• Layers – show, hide, and lock parts of the model; a node in several layers.
• Notes – text attached to nodes and relationships that moves with them.
• Style, Simple mode, and Square mode – colors, sizes, themes, and the two modes.
• Arrange – automatic layout with the fewest crossings.
• Keyboard shortcuts – every key and gesture.

In and out

• Export – Cypher with constraints, JSON, SVG, and PNG.
• Import and merge – JSON, files, pasted names, and the merge question.
• Draw an existing Neo4j database – two queries, paste the results, get the structure.

Together

• Accounts, sharing, and collaboration – sign in with a code, share with named people, edit in real time, version history.
• AI assistants – let Claude, ChatGPT, or another assistant draw and edit models.
