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)

Starting with GroIMP 2.2.2 it is possible to enable auto redrawing of the 2D Graph in the preferences. This will automatically redraw after every graph changing event.

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.
