In this window graph data from files or the standard output of programs can be read in.
The data has to be in one of the two formats that CaGe
When reading graph data representing plane graphs of very different nature, finding
good 2D and 3D embediings efficiently is especially difficult and the assistance
of the user is asked.
The user can keep embedding information contained in the data or
take that information as a starting point for further refinement.
The embedding programs in CaGe are specialized on certain kinds of graphs, so if a new
embedding must be computed, the user
has to describe which shape he would expect the graphs to have in order to give a hint
which embedder should best be used. The user has to choose whether the expected threedimensional shape is
- rather flat
- rather spherical
- rather tubular
Furthermore the user can increase or decrease the number of steps of the embedding routine.
