Graphviz bold font attribute

Question

I would like to change font attribute as the example below

Is there any way to change the font of just few words inside a label instead of using the global attribute change fontname="times bold italic" ? I need to convert to png.

Answer 1

You may use HTML-like labels in graphviz and define labels with partially bold text:

mynode [label=<<FONT FACE="boldfontname">bold text</FONT>>]

Or use the <B> tag:

mynode [label=< <B>bold text</B> regular text >]

Answer 2

If you are really desperate, you could also copy&paste bold unicode strings into your graph description, for example using the following website:

Apparently, this too does not work in all setups.
