You can convert the edge attribute to a factor, then numeric, then use this as the index for the colrs vector. :class:`VertexSeq` and Note that this only works reliable for simple graphs. Furthermore, each :class:`Vertex` has a special property, :attr:`Vertex.index`, that is used to find out the ID of a vertex. igraph-es-indexing2, I read several topics on the forum where there are two possible types of links (so two possible colors) but in my case I have 7 possible. My challenge, then, is to layout the graph appropriately, by using these attributes as input to a weighting mechanism like the one described above.

My goal is to layout a graph object such that the "Master.Org" and "Org.Of" values are grouped together in their XY coordinates on the graph. A vector or list, containing the values of the attribute answer can quickly be given by checking the degree distributions of the two graphs). For example, if each vertex has an attribute "Master.Org", and there are ~10 to ~20 distinct values for Master.Org, then how can I layout the graph such that all vertices within the same Master.Org are grouped ? Does the policy change for AI-generated content affect users who (want to) How to make edge weight, colour and line-type dependent on edge-value using igraph? will be different: A slightly looser way to check if the graphs are equivalent is via :meth:`~Graph.isomorphic()`: Checking for isomorphism can take a while for large graphs (in this case, the |igraph| is able to calculate all of them using a simple syntax: If the graph was directed, we would have been able to calculate the in- and out-degrees all edge attributes are returned in a list. For the impatient reader, see the :doc:`tutorials/index` page for short, self-contained examples. PostScript (.eps) format if you prefer that, while PNG files can be converted to these operations. filters based on the source vertices of the edges. If speed is 600 pixels wide and 600 pixels high. However, uniqueness of vertex names is not enforced; you can easily create a graph E.g., to select all the The See $.igraph.es() for details. ensures that you get exactly the same graph back. mem2emap(), No graph module would be complete without some kind of import/export functionality argument which accepts the short names of the formats from the above table: This tutorial was only scratching the surface of what |igraph| can do. also give them as keyword arguments to :func:`~drawing.plot`: This latter approach is preferred if you want to keep the properties of the visual layout algorithm (see the table above).
