Questions tagged [neato]

Neato is a program in the graphviz toolkit for generating visual layouts of undirected graphs. Its layout heuristic creates virtual physical models and runs an iterative solver to find low energy configurations. Neato has a wide variety of uses, but its intended applications are in telecommunication networks, computer programming and software engineering.

From the NEATO User's manual...

NEATO is a utility that draws undirected graphs, which are common in telecommunications and computer programming. It draws a graph by constructing a virtual physical model and running an iterative solver to find a low-energy configuration. Following an approach proposed by Kamada and Kawai [KK89], an ideal spring is placed between every pair of nodes such that its length is set to the shortest path distance between the endpoints. The springs push the nodes so their geometric distance in the layout approximates their path distance in the graph. This often yields reasonable layouts [Ead84][FR91]. (In statistics, this algorithm is also known as multidimensional scaling. Its application to graph drawing was noted by Kruskal and Seery in the late 1970s.)

NEATO is compatible with the directed graph drawing program DOT in sharing the same input file format and graphics drivers [KN91]. Since the file format includes both undirected and directed graphs, NEATO draws graphs prepared for DOT, and vice versa. Both programs have the same options for setting labels, colors, shapes, text fonts, and pagination, and for generating code in common graphics languages (PostScript, raster formats such as GIF and PNG, SVG, FrameMaker MIF, HPGL/2, and web click maps). Both work with DOTTY, an interactive graph viewer for X windows. (The lneato command script runs neato from an interactive window.)

how to use neato with spline and avoid mutual edges overlapping?

I have a directed graph with ~20 nodes that I need to have their positions fixed. So, I'm using neato to generate my svg file. The problem is that if I use the straight lines, I have edges overlapping some of the nodes. If a set -Gsplines=true…

Border around graph

I would like to create an border around the graph which is getting generated with nop2 engine. digraph { a[pos="0,0!"] b[pos="100,0!"] a -> b } This gets translated into this : which does not have an border around it. How can we generate an…

Is there a way to draw cluster with neato?

I have a graph that is best presented with neato. However it seems that neato doesn't support cluster? Here is a test code and its graphic: graph G { subgraph clusterA{ 1; 2; 3; } } I also ask this on GraphViz forum

how to compartmentalize a big graph using twopi

I have a rather large graph in DOT, which I render using neato and I'm more or less able to distinguish its main clusters using a lot of len=... attributes. I wanted to experiment with twopi, because I like a lot the way it renders, but I see that…

Visualizing networks in GWT

I'd like to integrate network visualization into my GWT app. I was thinking of using JUNG (check out this question) or neato to do the layout work and GWT-Graphics to do the drawing. It's also possible to combine GWT-Graphics with Processing and…
