DOT file with 1000+ nodes renders blank file

Having trouble with a graph that contains 1000+ nodes. For some reason, no matter what format it is rendered to, it comes out completely blank. Trying to have the graph rendered with the following:

in file:
strict digraph G {
layout=dot;
overlap=false;
splines=true;
pack=true;
start="random";
sep=0.1;
edge[len=1];
node[shape=oval];

in cmd:
dot -Goverlap_scaling=-10 -Goverlap=prism -Tpdf sample.dot > sample.pdf

Any help would be appreciated, thanks

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

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.

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

≪ Previous: Laying Out A "Community Structure"

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.

# 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:

Weight not working with sfdp ?

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

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.

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"] }

Display of Very Large/Wide Graph

≪ Previous: sfdp label_scheme example?

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.

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
