I generate SVGs using Graphviz. When embedded in HTML, the nodes, edges and arrows show an "_anonymous_0" tooltip. Can I get rid of these from within GraphViz?
Found by trial and error :-)
digraph "my title" {
tooltip=" "
node [tooltip=" "]
edge [tooltip=" "]
...
}
disables the automatic generation of tooltips.
an empty string
tooltip=""
does not(!) disable the generation.
If your dot source start something like this:
digraph {
it may help to use the following:
digraph "" {
It looks like the name of the graph (digraph mygraph { ) is transformed to a title element (<title>mygraph</title>). If you omit the name, *anonymous_0* is used instead. But if "" is used, no title element is being created.
There may be a better solution to this though...

Following is code using dot language.
subgraph cluster1
{
node[style=filled];
color=blue;
b0->b1;
label ="Tada"; // I want this to show as underlined.
}
You can use HTML-like labels and the <u> tag:
digraph cluster1
{
node[style=filled, color=blue];
b0->b1;
label = <<u>Tada</u>>; // I want this to show as underlined.
}
This is the result:
Note that your color=blue statement wasn't applied to any element. I moved it into node.
As pointed out in the comments, this currently only works for svg output. I tried with png and pdf on my Mac running 10.14.6 and they weren't underlined.
I need to plot nodes which have two rows. The top row is node name, and the bottom row is a condition. I am currently using the html-style table tag to achieve this. However, somehow I dislike this way. So, I am wondering if there is a more concise way without using html-style tags to do this. Note that I don't want to change rankdir=TB to rankdir=LR.
An example of my current approach, including code and output, is attached below. Thank you in advance.
digraph G {
node [shape=Mrecord]
aNode [ label=<
<table border='0'>
<tr><td bgcolor='gray'>nodeName</td></tr>
<tr><td>condition</td></tr></table>
> ];
}
Putting {} around the text in your label will change the direction of the record separators.
digraph {
graph [rankdir=TB];
node [shape=Mrecord];
item [label="{one | two}"];
}
In my Graphviz graph (written in DOT), I want each node to have a label, but in addition to that, I want some nodes to have a small caption denoting some other unique value for that node. For example, if this were for a history diagram, a node's label might be something like "Birth of George Washington" and the caption might read "See also: American Revolution."
This is fairly flexible, so the caption doesn't necessarily need to be inside the node, but I do need some other way of putting text that clearly isn't part of the label (e.g. is a different size, possibly a different color) and is in a different location but is still clearly a part of the node.
Is there any way to do this?
To place captions outside the node, you may use xlabel:
digraph g {
forcelabels=true;
a [label="Birth of George Washington", xlabel="See also: American Revolution"];
b [label="Main label", xlabel="Additional caption"];
a-> b;
}
forcelabels=true makes sure no xlabel is omitted.
A second option is to use HTML-like labels:
digraph g {
a[label=<Birth of George Washington<BR />
<FONT POINT-SIZE="10">See also: American Revolution</FONT>>];
}
What I want to ask is that we can draw figures using dot but is it possible to give a name to that figure and that name comes below that figure?
If your question is about graphviz, here's how to add a label below the graph:
digraph {
1 -> 2;
labelloc="b";
label="Graph label";
}
I need to print a large number of graphs using Graphviz DOT. To distinguish which input each graph corresponds to, I want to also have a caption for each graph. Is there anyway to embed this into the DOT representation of the graphs.
You can use label to add a caption to the graph.
Example:
digraph {
A -> B;
label="Graph";
labelloc=top;
labeljust=left;
}
labelloc and labeljust can be used to determine top/bottom and left/right position of the graph label.
All the details and other attributes that can be used to modify the label (font etc) in the graphviz attribute reference.
Tip: Define the graph label end of your dot file, otherwise subgraphs will inherit those properties.
Graph's can have attributes just like nodes and edges do:
digraph {
graph [label="The Tale of Two Cities", labelloc=t, fontsize=30];
node [color=blue];
rankdir = LR;
London -> Paris;
Paris -> London;
}
That dot file produces this graph.
If you are looking for a way to add a caption to a Graph object of graphviz in python. Then the following code can help:
from graphviz import Graph
dot = Graph()
dot.node('1','1')
dot.node('2','2')
dot.edge('1','2', label="link")
dot.attr(label="My caption")
dot.attr(fontsize='25')
dot.render(view=True)
Output:
