Interactive Aggregation

This demo shows how to analyze a graph by aggregating groups of nodes.

Via the context menu, groups of nodes of the same color or shape can be aggregated giving different insights about the graph.

For example, aggregating all nodes by color shows that there are no connections between purple and green nodes, while blue nodes are connected to both other colors. Aggregating by shape and color shows that there are no connections between rectangular nodes of different color and no connections between green nodes of different shape.

The demo makes use of the AggregationGraphWrapper class, that allows for aggregating graph items by hiding items and adding new items to a wrapped graph.

Things to Try

• Right-click on a node to open a context menu with the different aggregation and expansion options.
• Aggregate all nodes with the same shape or color by selecting "Aggregate Nodes with Same ...".
• Separate an aggregation node again by selecting "Separate".
• Right-click on an empty location on the canvas and select "Aggregate All Nodes by ..." to group all nodes by shape or color.
• Right-click on an empty location on the canvas and select "Separate All" to show the whole graph again.
