graph-layout

i am using this dot-Code for my Test: digraph G { edge [dir=none]; p1 [shape=circle,style=filled,label="",height="0.01",width="0.01"]; q1 [shape=circle,style=filled,label="",height="0.01",width="0.01"]; q2 [shape=circle,style=filled,label="",height="0.01",width="0.01"]; q3 [shape=circle,style=filled,label="",height="0.01",width="0.01"]; {rank=same; father->p1; mother->p1}; {rank=same; q1->q2->q3}; {rank=same; son1; daughter1; daughter2}; p1->q2; q1->son1; q2->daughter1; q3->daughter2; } My Java Code to create the Graph is the following: Graph graph = null; graph = program.getGraph();

I have perfection paralysis when it comes to producing something graphic. If symmetries of the visual have not been fully explored, I have a harder time comprehending what is going on. I am a very visual learner as well, and I LOVE to simplify things that I just learned and draw them on paper. Graphviz is a nice tool to draw thing automatically, but it could be better. Let's start with an example of a good graph )a state machine rather). Never mind the quality (it can be redrawn with a better tool) this one is almost perfect, except that I would turn it counter-clockwise 45 degrees to make the

What algorithms are good for interactive/realtime graph-drawing for live data and direct-manipulation? Failing that - what libraries do you use to draw graphs? Suggestions; Prefuse information-visualization toolkit any others? BTW- I mean graphs in the graph-theory sense - points and lines any language by live I mean the graph should be manipulatable once on screen. I would recommend any library that Jeff Heer has worked on: D3 Protovis Flare Prefuse I believe all three projects are open source. Jeff Heer is pretty good at referencing papers in his code at least in the Prefuse library. Looking

By graph here I mean something resembling these images: The ideal solution would: use only managed code allow output to a bitmap image allow output to WPF elements include some kind of interactive surface for displaying the graph that supports zooming, panning and reorganisation of nodes I'm also interested in hearing about projects that could potentially be used as the starting point for this kind of work. If it requires some development to achieve what I want, then I'm prepared to tackle it. The most complex portion of this goal seems to be obtaining the graph layout in a reasonable time

I'd like to implement the following mockup with dot: So far I've got this much: digraph G { graph [rankdir = LR, splines=ortho] unit [shape=box, width = 2, height = 10]; more_different_unit [shape=box, height=4]; other_unit [shape=box, height=4]; unit -> other_unit [label = "foo"]; unit -> other_unit [label = "bar"]; unit -> other_unit [label = "bar"]; unit -> other_unit [label = "bar"]; unit -> other_unit [label = "bar"]; unit -> other_unit [label = "bar"]; unit -> more_different_unit [label = "bar"]; unit -> more_different_unit [label = "bar"]; unit -> more_different_unit [label = "bar"];

For an iOS application I'm making I need to show groups of elements grouped together according to their type, and different groups of types separated from each other in a nicely done layout. I thought of using an undirected graph, with the grouped nodes all pointing to each other in a sort of circular reference, and then each group as another "meta-graph" with their nodes point at each other in a circular reference as well, hoping that together with a good graph layout framework this could be displayed nicely. Unfortunately, the only framework I keep hearing of is graphviz , but that doesn't

I have a graph that has a tree as its backbone. So I have, for example a node A with children B, C, and D. Assuming the graph is being drawn top-down, A will be on one level, then B, C, and D. I would like to force graphviz to lay them out in B, C, D order within their rank. Is this possible? If so, how? If there are only A, B, C, and D, I can get this effect by just putting B, C, and D in that order in the input dot file. But if there are other edges out of B, C, and/or D, sometimes the order gets scrambled. That's what I would like to avoid. This can be achieved with "invisible" edges as

I need advice for rendering an undirected graph with 178,000 nodes and 500,000 edges. I've tried Neato, Tulip, and Cytoscape. Neato doesn't even come remotely close, and Tulip and Cytoscape claim they can handle it but don't seem to be able to. (Tulip does nothing and Cytoscape claims to be working, and then just stops.) I'd just like a vector format file (ps or pdf) with a remotely reasonable layout of the nodes. Anthony Liekens Graphviz itself provides a solution for rendering large graphs. Namely, Graphviz includes sfdp , a multiscale version of fdp (also in graphviz, similar to neato) for
