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!

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

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"]
}

Weight not working with sfdp ?

Hi,
 
I am interested in the weight attribute for edges and I am drawing large graphes (may be 50k nodes, 1M edges), so I wish to use sfdp. I have read here (http://graphviz.org/content/attrs#dweight) that weight can be used with sfdp. And this example (http://www.graphviz.org/Gallery/undirected/gd_1994_2007.html) seems to use weight.

Making graph human friendly/readable (500 nodes, 1600 edges)

# First time posting, sorry if this is double-post! 
I have decided to lear DOT language, which looks fantastic. I decided to make a project for making a graph for RPM building. I scan all the recipes to build RPM packages and also add information about required patches and imports. Currently my graph has <500 nodes and >1600, and the size should be stable +/- 50-100 nodes/edges from time to time.
Here is what I have now:

Can edge length be controlled in a force-directed graph?

I'm building a graph using sdfp/gvmap using the basic command workflow in the one gvmap gallery item.  My dataset has about 6K nodes. 
I've built clusters of nodes by connecting them to a single node with invisible edges.  In the graph this produces country-like formations.   Inside these clusters, there are many hundreds of connected edges. 
If I graph just these clusters, they are evenly spaced in the output image.

Laying Out A "Community Structure"

Thank you in advance to anyone that can offer some advice on this issue. I am trying to layout undirected graphs with nodes ranging from 200 to 2000. currently I am using SFTP, but will can change that if that is indeed the problem. I am trying layout my graphs in a "Community Structure". Please see this URL for definition. There is only one diagram on the Wiki page and is exactly what I want. http://en.wikipedia.org/wiki/Community_structure When I try to layout the graphs the different "Communities" get pushed together like Venn diagram.

Trying to generate gallery sfdp graph using code provided

Hi,

I would like to generate a large graph like this;
http://www.graphviz.org/content/root
So I was trying to use the example code as it is to begin to understand how it works;
http://www.graphviz.org/Gallery/undirected/root.gv.txt
However I can't get this to work out-of-the-box.

The command I tried is
sfdp -Goverlap=prism -Tgif root.gv > root.gif
with the following error;
sfdp: graph is too large for cairo-renderer bitmaps. Scaling by 0.000220406 to fit
sfdp: failure to create cairo surface: out of memory
Segmentation fault
