For a given graph containing vertices, edges, and a signal associated with the vertices, the PathwaySpace package performs a convolution operation, which involves a weighted combination of neighboring vertices and their associated signals. The package then uses a decay function to propagate these signals, creating geodesic paths on a 2D-image space.
