In one implementation, a method can include receiving data characterizing a plurality of scenarios. A first scenario of the plurality of scenarios can include a first plurality of models associated with a plurality of model types. The method can also include determining a first visual representation of the first scenario for display in a graphical user interface (GUI) display space. The first visual representation can include a first plurality of graphical objects indicative of the first plurality of models. The first plurality of graphical objects can be arranged in a plurality of columns indicative of the plurality of model types. The first plurality of graphical objects can be connected by a first line. A first path of the first line in the GUI display space can be based on one or more grids. The method can further includes displaying, in the GUI display space, the first visual representation.
