*[Cross posted on StackExchange.](https://mathematica.stackexchange.com/questions/145417/importing-multigraphs-with-edge-properties)* ---- [Mathematica cannot represent edge properties in multigraphs][1] (except for EdgeWeight, EdgeCapacity...
Hello, DocumentationHelpLookupPacletURI is broken on Linux in 11.1. It opens a notebook window that has no search bar or navigation buttons. I thought it would get fixed for 11.1.1, but it wasn't. So now I am asking here: Is there a...
*[This has been cross-posted to StackExchange](https://mathematica.stackexchange.com/q/144594/12)* ---- Mathematica has a layout algorithm [to plot planar graphs without edge crossings][1]. This typically produces an ugly triangular layout...
The following bug caused me some headache, so I thought I would share the workaround. Sometimes trying to set VertexCoordinates on a graph failed mysteriously, at other times it worked fine. I could not figure out why. It turns out that it...
Hello everyone, I found this feature example page, which unfortunately seems to be empty in all versions I have installed. https://reference.wolfram.com/language/example/CreateYourOwnGraphStyle.html I was wondering if this meant that it was...
In version 10.x, there were many featured examples in the documentation for several application areas (see screenshots below). Where can I find these collections in version 11.x? The individual pages still seem to be present, but I cannot find a...
[Cross posted on StackExchange.][1] ---- Hello everyone, How can I retrieve the complete list of vertex (or edge) property names for a graph? I am looking for a way that is first robust (must work on *any* graph), then efficient (even for...
For those who use NeighborhoodGraph, be aware: when called with default options, this functions performs much worse than it should. The reason is that it computes a graph layout even if the result is never displayed. Let's see how slow it is...
It seems that Maping a function over a SparseArray can produce a result where one of the explicit values in the array is the same as the background value. It seems to me that this is a bug because other functions appear to assume that an...
This is a proposal for adding functions that can transform or rename arbitrary graph properties, such as EdgeWeight`s. ## Why? When importing a graph that has properties, the properties will often be in an undesirable format. One may need to...
