The Graph provides a visual workspace where entities and their relationships are displayed as an interactive network. Graph fundamentals showing the basic structure and components ## Core Concepts The Graph operates on a node-and-edge model where entities are represented as nodes, and relationships between them are shown as connecting edges. ### Nodes Nodes represent individual entities in your investigation, such as people, organizations, locations, or digital assets. Each node contains associated data and can be expanded to reveal additional connections. ### Edges Edges are the connections between nodes, representing relationships like transactions, communications, associations, or other meaningful links between entities. ## Creating Nodes Right-click anywhere on the graph to open the node creation menu. Right-click menu showing filtering options, layout controls, and node type creation The menu provides options for filtering nodes, changing graph layout and appearance, and creating specific node types. ### Filtering Node Types Use filtering options to display only specific node types on the graph. Filtering options menu showing node type checkboxes with node counts Select node types to show or hide, with quick actions to show all, hide all, or reset filters. Each node type displays the current count of matching nodes on the graph. ### Node Categories Nodes are organized into categories, each containing specific node types available for creation. See the [complete directory of all nodes](/graph/nodes) for comprehensive details. Node categories menu showing Personal, Device, Companies & Organizations, Network, Geographic, Cyber, Hardware & Services, Social, Registration & Tracking, and Transportation categories ### Creating a Node Select a node type to open the configuration form. Enter values for available fields—all fields are optional. Configure Person modal showing optional fields for first name, middle name, last name, and age ### Quick Create Type a recognizable value—such as a domain, email, phone number, or name—into the search bar to trigger quick create suggestions. Quick create suggestions showing domain and website creation options for intrace.ai ### Nodes on the Graph Nodes appear on the graph with an icon on the left, the display value in the center, and a copy button on the right. Some nodes include tags below the main value. While nodes can contain many fields, only one display value is shown on the graph.
