Still wondering about directed graphs drawn from AppEngine

With reference to another case of pretty much the same question I have, Brightside asked: http://stackoverflow.com/questions/2264157/library-to-render-directed-graphs-similar-to-graphviz-on-google-app-engine The accepted answer was "canvis", which looks very cool from a rendering perspective, but canvis just does the drawing. It still n...

How to set fixed depth levels in DOT graphs

I'm creating a DOT graph visualization from a tree-like data structure but am having difficulties setting fixed level depths based upon data type. For example, if I had 4 nodes in a tree and A denotes a specific data type and B represents another it would like Graph_1: ROOT ...

Graphviz size/pagesize attribute seemingly ignored

How does one set the size of the output image in GraphViz via the DOT format? I'm using QuickGraph and this technique to render a GraphViz. As in the example below, I'm trying to set the maximum size of the rendering. I've tried lots of variations on size (interpreted as inches or as pixels) and pagesize, both, each. Doesn't matter. ...

How to force Graphiz tool (dot, neato,...) to accept some initial node placement

Is there a way to force any Graphviz tool (dot, neato,...) to accept some initial node placement and keep them in this position, while placing the remaining nodes using its standard algorithm ? I have tried to play with the "pos" node attribute in Neato, without success. Thanks in advance ! JCLL ...

Reducing graph size in graphviz

Does anyone have any general tips for reducing the size of a graph generated by graphviz (size as in area, not as in file size). I have a fairly large graph (700 nodes). I set a smaller font size for each node, but it seems to only reduce the font size and not the actual node size. Are there any attributes to reduce the overall amount o...

free visual editor for graph (dot) files

Is there a free (as in "cheers"), linux-compatible, interactive visual editor for graphviz or other graphs? aptitude seems to be drawing a blank. edit: "cheers" means both "beer" and "speech". meta-edit: I guess it should be "free as in beach". edit 2: Maybe a suitable svg editor would be a more realistic goal. I basically want some...

Place edge label on the other side

This may be related to question 2350617: I have the following graph, which I visualize using the command dot -Teps g.dot > g.eps: graph triple { node [shape=box]; User; Object; Tag; node [shape=diamond,style=filled]; Triple; { User -- Triple [label = "1"]; Object -- Triple [label = "1"]; } { r...

graphviz Tree Layout

Hi, I am using graphviz for the first time. I just need a tree layout so that all the childs are at the same level. For example, A->B A->C A->D THEN B, C AND D SHOULD BE AT THE SAME LEVEL. Following is the code I am using. digraph unix { size="6,6"; node [color=lightblue2, style=filled]; "A:1000" -> "B:300"; "A:10...

Software to draw graphical models in plate notation

So I see graphical models expressed in plate notation in research papers and online all the time (for example: http://www.cs.princeton.edu/~blei/papers/BleiNgJordan2003.pdf). Is there a quick and easy way to produce these?? I've searched and searched but all I've found are solutions like GraphViz which are really way more powerful than...

Is This a “Large” GraphViz Chart, and How to Fix it?

Hi, I started using GraphViz yesterday in order to visualize the relationships between some things—a project I’ve been wanting to tackle for quite a while now. So far, I’ve gotten it pretty well done, but there’s a few things I’m struggling with, specifically getting the chart to look good and how long it takes to process the DOT file—...

Making a Legend/Key in GraphViz

Hi, I’d like to include a legend or key in my GraphViz diagram, something like the mock-up below. I’m having trouble figuring out what code to use though; the best I can get are the attempts in the second graphic. I also want to put it in a corner, but the only coord I know for sure is the bottem-left: pos="10,10!". Does anyone know ho...

C++/STL Graphviz and Boost - Seg Fault Problem

I am using the dot language to create a graph using Boost. My Graphs are huge and I am trying to delete graphs that are no longer used. Under boost/graph/graphviz.hpp I added a function to remove a vertex: virtual void do_remove_vertex( const node_t& node) { bgl_vertex_t v = bgl_nodes[node]; clear_vertex(v,graph_); ...

As title,I want to draw an image of ELF file format.The ELF Header has offset of program headers table and section headers table,so I want to use two arrows pointer to point out the relationship.But the edges overlap the node(record) even after I have overlap=false and splines=true set.I have search for a while,but my situation is that t...

graphviz dot: how to insert arrows from a node to center of an arrow

Hi everyone, I try to create diagrams for MPLUS analyses with dot from the graphviz package. Does anybody have experience with using dot to visualize structural equation models/latent class mixture models? There is especially one feature that I can't figure out how to do beautifully: I need arrows from nodes to the center of another ar...

Drawing large graph with graphviz

Hello guys, I have here generated a large .dot file of my facebook friends' graph with fb-map. It has 287 nodes and almost 2000 edges. I'm using dot and neato to generate a .png image, using the overlap="orthoyx" paramethers, but it doesn't give a nice effect. Too many overlapped edges. Do you know any set of options to manage such hug...
