Filter for drawing directed graphs.


I have the following code:

digraph g {
graph [rankdir="LR" ,compound="true" ];
subgraph cluster0 {
graph [label="Ready\n\nAllowed Purchaser Operations:\noperation1,operation2\n\nAllowed Supplier Operations:\noperation1,operation3" ];
1 [ shape="none" ,fontcolor="white" ];
subgraph cluster2 {
graph [label="Paused\n\nAllowed Purchaser Operations:\noperation1,operation3\n\nAllowed Supplier Operations:\noperation2,operation3" ];
3 [ shape="none" ,fontcolor="white" ];
subgraph cluster4 {

Rendering automata

Hi all,

I'm using GraphViz to render weighted automata. They are generalizations of the usual DFA/NFA: there are states, and transitions. In the weighted case, in addition to a label, the transitions may have a weight (denoted in angle brackets in my example below). Initial and final states also have a weight.

How to use id for two different nodes with the same name

Hi everyone, I have the following issue: I'm making a tree graph in which some of different nodes have the same name (e.g. West (Mande) and West (Dogon)). Unfortunately, the documentation doesn't give an example of how to use the id attribute to create two unique nodes which would be displayed under the same name.

Arrows messing up flow chart

Hey everyone,

I have a flow chart that has a left-right topology. When I leafe out the arrows leaving from decision diamonds everything looks just the way I want it to look like. But as soon as I add them my output looks crazy. Does anyone have an advice for me? I really appreciate it.

This is the corresponding code for attached image:

digraph uart_flow{

node start [style = rounded, shape = rect, label="RX event"]
node handler [style = rounded, shape = rect, label="Call\nhandler"]
node header_done [shape=diamond, label="Header\nreceived?"]

Beginner help: layout of nodes within clusters

I'm trying to use Graphviz for a purpose it wasn't really intended for - drawing highly detailed layout diagrams of my office network. Within my graph I'm creating a cluster for each network device. Within each cluster I'm creating nodes for each device port.

Object's atributes

I have posted the following question on stack overflow:

Can anybody help me with that?

Thank you.

Node with edge that ends on it's own cluster boundary

Hi I am wanting to produce a graph that has a node with an edge that ends on it's own cluster boundary.

Is this possible?


digraph G {
subgraph cluster0 {
Satelite; Puppet; "Bastions";

Bastions->Satelite [lhead=cluster0];

So that the edge leaving Bastions, gets connected to boundary that contains Satelite (which is the same boundary that contains Bastions.



Equal nodes?

Is there a way to tell dot that a node and another one are the same, even if they have different labels?

I have these nodes (which are names of sets)

(q0 q2 q1)

(q0 q1 q2)

Also, I have these two:

(q2 q1) (q1 q2)

So, in set theory, they're equivalent.

But Dot doesn't know that, so instead, it creates 2 different nodes. I could make the combinations of items in the sets, and then put them there but Dot draws them even if there's no edge that leads to them.

Is there a way to:

Installing More Image Formats

I recently installed Graphiz on CentOS using the rpm on this page:

When trying to run dot -Tbmp I find that it isn't capable of generating any images. It just says:

Format: "bmp" not recognized. Use one of: canon cmap cmapx cmapx_np dot eps fig gv imap imap_np ismap pic plain plain-ext pov ps ps2 svg svgz tk vml vmlz xdot xdot1.2 xdot1.4

Is there any way to install more image types so I can actually create image files with this?

performances of 2.34 with images (bis)


I am not able to attach the resources (on dot file and 2 16x16 png images referenced many times in it) on which I am encountering the issue (a HTTP error...), nor even reply to the previous message (answer considered as a spam...). So please find below the dot specification. For the images, I think you can use any 16x16 png image.

I am running the dot.exe under windows with the following options: -oD:\MyGraphs\graph1.svg -Tsvg -Tcmapx -NURL=\ -oD:\MyGraphs\ D:\MyGraphs\

It works fine with no (or less) "img" references.
