How It Works

Understanding dependency visualization with Delineate

01

Graph Database Storage

We use Neo4j, a powerful graph database, to store package information and relationships. Each package is represented as a node with properties like name, ecosystem, and description. Versions are stored as separate nodes, connected to their parent package through HAS_VERSION relationships.

02

Package Search

When you search for a package, we query the Neo4j database to retrieve the package node and all its related version nodes. We also follow DEPENDS_ON relationships to gather information about dependencies, creating a complete picture of the package ecosystem.

03

Graph Construction

The data retrieved from Neo4j is transformed into a graph structure with nodes and links. Packages, versions, and dependencies are represented as nodes with different colors, while relationships between them are shown as connecting links in the visualization.

04

Interactive Visualization

The graph is rendered using a force-directed layout algorithm that positions nodes based on their relationships. You can interact with the graph by dragging nodes, zooming in and out, and hovering over nodes to see detailed information. The visual representation makes it easy to understand complex dependency chains at a glance.
