User Guide Overview¶

This guide covers how to use GraphForge for graph analysis and construction.

Topics¶

Cypher Query Language ¶

Learn the openCypher query language - GraphForge's primary interface for working with graphs.

Graph Construction ¶

Build graphs programmatically using the Python API.

Core Concepts¶

Graphs¶

A graph consists of nodes (vertices) and relationships (edges) connecting them.

Nodes¶

Nodes represent entities in your graph. They can have: - Labels - Types or categories (e.g., Person, Product) - Properties - Key-value pairs with data

Relationships¶

Relationships connect nodes and can have: - Type - The nature of the connection (e.g., KNOWS, PURCHASED) - Direction - From one node to another - Properties - Additional data about the relationship

Patterns¶

Cypher uses ASCII-art patterns to describe graph structures:

(a:Person)-[:KNOWS]->(b:Person)

This pattern matches two Person nodes connected by a KNOWS relationship.

Query Flow¶

MATCH - Find patterns in the graph
WHERE - Filter results
RETURN - Specify what to return
ORDER BY - Sort results
LIMIT - Limit number of results
