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.)

Why is pygrapviz(neato) overlapping my clusters?

I am trying to draw a graph from the following dot file. The neato algo is overlapping the nodes while the dot one puts the clusters side by side when I want them to be like in a top down order. This was added here because StackOv says I did not add…

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…

Node layering in Graphviz

I'm creating a graph using Graphviz (compiled with neato). This graph contains many overlapping nodes which is perfectly fine. However, there is a group of large nodes which I prefer to always be on top of other small nodes - even-though I prefer to…

Graphviz edge label position - graphviz ignoring label positions when control points not defined for edges

Graphviz (using neato) ignores label positions when control points are not defined for edges. I can brute force my way to positioning the labels, but I'm doing this in ignorance of the real problem. Is there a way to stop graphviz overwriting lp,…

Graphviz: how to use neato with very large graphs with subgraph clusters?

I have a large, but not really huge(?) graph, with 13 subgraph clusters containing about 100 nodes and 3,147 edges. Dot crashes on Windows and seg faults on Linux. This question suggests that the solution is to use neato, rather than dot. But, this…
