using gvmap as a library

I've been pleasantly surprised by the quality of xdot rendering, using Graphviz as a library.
Actually, a simple translation from xdot output to Qt graphics primitives now yields a performant and accurate display of complex graphs.
I think I will try to bypass xdot/libxdot to get further memory/time gain, using gvrender_engine_t...

Now my question: it's possible to get gvmap working at the same level of, say, xdot, thus avoiding FILE IO ?
I understand from license terms I could compile the relevant parts, or I'm wrong here ?


no complement clustering info in dot file with Gvmap

Following the Gvmap example from http://www.graphviz.org/Gallery/undirected/gd_1994_2007.html and cluster example from http://www.graphviz.org/content/cluster, I tried to create a gvmap file. But it always tells me that there is "no complement clustering info in dot file, using modularity clustering". I am frustrated with this message.

how do I use gvmap in graphviz (windows installer)?

Hello all,

I'm looking into using gvmap, but I can't figure out how to use gvmap.

In this page (http://www.graphviz.org/Gallery/undirected/gd_1994_2007.html),

it simply says

"Note that input graph to gvmap must first be laid out, with overlap removed. E.g.,

sfdp -Goverlap=prism -Gcharset=latin1 gd_1994_2007_8comp.gv | gvmap -e | neato -Ecolor="#55555522" -n2 -Tpng > gd_1994_2007_8comp.png"

but where do I put sfdp ... command?

All I have figured out so far is to create a graph layout using dot language in gvedit.

Can somebody please help?


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.

Controlled Edge Length in Spring Graphs?

I've been working on an approximately 6000 node graph using the svdp/gvmap pipeline - just the command that is described in the one gvmap gallery entry. In my graph, I create primary clusters intentionally by linking common nodes to a single node with invisible edges. These would generate what look like countries in gvmap. These clusters have many thousands of internal connections. These clusters are also connected to one another. The effect of these inter-cluster edges is that all they are pulled into the center of the image, looking like one large land mass.
