Planar Graph Layouts

What are some edge overlap minimization techniques when laying out a graph? (Preferably related to GraphViz) Also are there any existing software that can layout a graph in a planar fashion? Current Layout - http://www.evecakes.com/doodles/master.gif The pink section in the upper left hand corner looks fine while the light blue section has some avoidable edge overlaps. For general graphs, the problem of a determining a planar layout of a graph with least edges crossing (the Crossing Number ) is NP-hard. So some heuristic methods are used (like the Force based layout algorithms). The page below

How can I control within level node order in graphviz's dot?

问题 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

Visualizing Undirected Graph That's Too Large for GraphViz?

问题 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. 回答1: Graphviz itself provides a solution for rendering large graphs. Namely,

问题 This post is a Community Wiki . Edit existing answers to improve this post. It is not currently accepting new answers. I have a data structure that represents a directed graph, and I want to render that dynamically on an HTML page. These graphs will usually be just a few nodes, maybe ten at the very upper end, so my guess is that performance isn\'t going to be a big deal. Ideally, I\'d like to be able to hook it in with jQuery so that users can tweak the layout manually by dragging the nodes
