The 2d Graph panel (panels/2d/graph) is a powerful tool for understanding and navigating the graph structure in smaller GroIMP models.

The menu of this graph allows to change the (layouts (Layout > Edit), to change between different Graph descriptors (Graph > Edit), to redraw the graph / reapply the layout (View > Redraw), collapse and expand all node (View > Collapse all, View > Expand all) and to save the currently displayed picture (View > Snapshot)

By double clicking on a Node on the 2d graph the node can be collapsed, meaning all its children are hidden. A collapsed node can be identified on the round shape (see image above lower right corner). Double clicking on a collapsed node expanse it again.

Node with more than 10 direct children will be automatically collapse when the 2D graph is opened.
