A class that provides basic layout management functions for a top-down geographic network map. Provides functions for scaling from 'Network Coordinates' to 'Image Coordinates' and vice-versa.

Any INetworkGraph that implements IElementLocatable can provide reverse-lookup capabilities, that is, can find network elements based on a point in the graph.

Indicates that the graphical output of an INetworkGraph will vary based upon a specific selected NetworkElement.

INetworkGraphs plot aspects of the information embedded into the electrical network model.

If PresentationMode is true when an INetworkGraph is drawing, the INetworkGraph should ensure that the primary information displayed by the graph is represented geometrically.
