Flow Filtering

This demo demonstrates how to dynamically show or hide items within the connecting upstream or downstream flows of a given node.

It uses the Neighborhood algorithm to find the successors or predecessors of the given node.

Things to Try

• Hover over a node to highlight items within the flow of the chosen direction.
• Select a node to hide its neighbors in the selected flow direction.
• Deselect the node by clicking on the empty canvas to show its neighbors again.
• Use the dropdown menu in the toolbar to set the direction for flow highlighting and filtering.
