Filtering and Highlighting

Groups (combos)​

To organize complex graphs, group nodes into collapsible clusters called combos. You can:

  • Create a single named group manually
  • Let Octostar auto-group nodes by their Concept type Combos display a label, an icon, and a count of the nodes they contain. Collapse a combo to reduce visual noise or expand it to reveal its contents.

Cropping​

Use the Crop button in the toolbar to reduce the graph to only the currently selected items. Everything outside the selection is removed from the canvas. This is useful for isolating a subgraph after selecting the nodes you want to focus on.

Interaction highlights​

Node and edge styles respond to interaction:

  • Hovered items gain a halo
  • Selected items receive a larger halo
  • Items highlighted for detailed inspection are wrapped in a hull decoration

Searching within the chart​

Use the Search field in the toolbar to find nodes by name within the current Link Chart. Matching nodes are highlighted on the canvas.
