The Exploration Canvas¤

The exploration canvas is the primary workspace in Graph Insights. It displays the exploration tree, allowing users to manipulate layout, throttle data density, and rapidly locate specific resources within the detailed groups.

Toolbar Controls¤

The top toolbar controls the exploration tree rendering and positioning.

Toolbar

Rendering and Positioning¤

  • Zooming: Use [+] / [-] buttons or the mouse wheel to adjust magnification.
  • Clearance: Adjusts the spacing between groups to reduce overlap.
    • Horizontal clearance: Adjusts left-right distance.
    • Vertical clearance: Adjusts top-down distance.
  • Fit to view: Click the “target” icon to center and zoom the exploration tree to fit all groups within the viewport.

History (Undo/Redo)¤

Graph Insights maintains a session history stack.

  • Undo: Reverts the last action (e.g., removing a filter).
  • Redo: Reapplies the undone action.

Undo Redo Controls

Rebuild on Undo

Some operations (e.g., user-defined classes operations) have persistent side effects that may require a rebuild of the exploration state when moving back in the history.

Group Rendering Controls (Max. resources)¤

To optimize browser performance and visual density, Graph Insights uses two different renderings for groups depending on their cardinality. Use the Max. resources dropdown to set the threshold.

Count-Only Rendering (Count > Threshold)¤

If a group contains more resources than the limit, it is rendered as a single disk displaying its cardinality. This mode is optimal for high-level topology analysis (before subsequent filtering).

Count-Only Rendering

Instance Rendering (Count ≤ Threshold)¤

If the count is below the limit, each resource is rendered as a dot within the group disk. - The number inside each dot represents its predecessor count (number of resources in the left group linked by the connection). No number means there is only a single predecessor. - The resources with higher predecessor counts are located at the center of the group.

Instance Rendering

Locate specific resources among those currently visible in the groups of the exploration.

  • Scope: Searches only rendered resources on the canvas. It does not query the backend for hidden data.
  • Behavior: Matches are tagged with a (temporary) orange flag and caption.

Flags Management

Use the Temporary flags menu that appears on the top left of the canvas to manage the persistence of the temporary flags.
