sfdp: Graphviz not built with triangulation library

Hi,
I have the following error message while trying to create a graph with the layout "sfdp". The error message is repeated 13 times.

dot mygraph.dot -Tsvg -o mygraph.svg
Error: remove_overlap: Graphviz not built with triangulation library

Changing the graph [layout="sfdp"] line in the dot file by any of dot, neat, fdp, circo or twopi works properly.
Any idea?

I'm running graphviz 2.34 on Mac OS 10.8.5 downloaded as a package, didn't compile myself.

Thanks in advance,
Pierre

Pinning nodes with sfdp

Is there a way to pin nodes with sfdp?

I can get it to work with neato by specifying pos=(x,y) and pin=true for my node but when I do the same with sfdp the pinned location is just ignored.

Thanks!

Unable to set min distance between node

hi, I have the following problem : I am trying to generate a graph showing the connexions between processes on my server. here is the result (this one is using sfdp) :   as you can see, there is a high concentration of edges around the center. In order to have a graph that is more easy to read, I am trying to set a minimum distance between two nodes, but I can't seem to make it work : I tried using fdp/sfdp and playing with the K instruction, I also tried using neato and playing with the edge len, but I don't see any change would you have any tip I could use ?

C and Graphviz

I'm working on a fuzzy pattern recognition system where, fuzzy relations, are represented by matrices.

We can look at such fuzzy matrices as adjacency matrices for directed graphs.

What I need to do is to draw the digraph related to a particular fuzzy matrix.

Is is possible to do this directly from my C code ?

Thank you in advance.

Syntax error in graph created by networkx, cannot run dot or neato

Hello, I am unable to visualize this graph created by NetworkXX (attached). It only has 60 nodes and 76 edges, but I suspect that the edge annotation data is too long for graphviz.

Using this command:

dot -T png chrIII-11,645,098-11,759,535_k75.dot > test.png

I get this error:

Warning: chrIII-11,645,098-11,759,535_k75.dot:75: syntax error in line 75 near ''

I also tried using `neato`.

The edge annotation data is important, and is a sequence of DNA characters so I'd prefer not to split it up, though I could. Any suggestions?
Thanks,
Olga

loading very large graph failed

I have installed graphviz on windows and it works fine when i load small graphs and also able to apply some layouts algo but when i load very large graph about 300000 nodes and 800000 edges it stops working and gives message to stop the application. PLease help me its urgent, thank you in advance

Does Graphviz support multi-color for single edge line like this?

I am not sure if Graphviz supports multiple colors for single edge like the following URL?

Fox example, for one edge, left half is of one color and right half is another color?

rendering bug

Hello,
I have a dot file who describe a graph but when i use it on Linux for produce a graph with the SFDP layout, the width and the height of the produce image don't change so the graph is illegible.But when i used the dot file on Windows or with an other layout in Linux,it works perfectly.
I try to use the different flags with command-line like -s or -Gsize but it doesn't work.

Display of Very Large/Wide Graph

Hello,

I'm dealing with a graphics hierarchy (SceneGraphs), and I want to display it.
I've already figured out how to get the code to automatically generate; displaying is my main issue.

I recently output the graph using size = "400,100"; I ran the program with the following: dot -Tgif graph1.sfdp -o graph1.gif
The reason I used .sfdp is because I heard it could handle thousands even millions of nodes. I believe I've only got around a 1000 edges, and less nodes, but it's just very wide. Using a .dot file gave the same results.

sfdp label_scheme example?

Is there a simple code snippet/graph available for demonstrating the sfdp label_scheme implementation:

I have tried to interpret |edgelabel|* with no success.

"...The value indicates whether to treat a node whose name has the form |edgelabel|* ..."

say a graph is in the format (duplication is intended):

graph G {
graph [label_scheme=1];
"A_1" -- "B_1" [label="test01"]
"B_1" -- "C_1" [label="test02"]
"B_1" -- "C_1" [label="test03"]
"C_1" -- "A_1" [label="test04"]
A_1 [label="A"]
B_1 [label="B"]
C_1 [label="C"]
}
