Geodesic2d maps every location on the graph as an orthogonal projection of the data onto a two-dimensional subspace. The nodes then represent the sub-space spanned by a pair of variates and the edges either a 3d- or 4d-transition of one scatterplot into another, depending on how many variates the two nodes connected by the edge share (see Hurley and Oldford 2011). The geodesic2d context inherits from the context2d context.
Contexts are in more detail explained in the webmanual accessible with
l_help. Please read the section on context by running
