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 >]

Note the restriction ... "In addition, all of these markups are currently **only available via the cairo and svg** renderers." – cmcginty Sep 13 '17 at 03:55
@cmcginty The OP wanted to convert to png, cairo should work perfectly fine for this - a downvote seems a bit harsh ... – marapet Sep 14 '17 at 12:23
@marapet I tried to remove the downvote when I figured out why it wasn't working for me, but the time had expired. If you edit the answer then SO will let me remove it. – cmcginty Sep 14 '17 at 19:08

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.

Unfortunately the characters do not render (square boxes with some code are shown). What was your setup to get this (last resort) solution working? – Saaru Lindestøkke Jul 21 '21 at 09:36
Frankly, I do not remember anymore. I guess it was just another option to try, but witout guarantees. – Radio Controlled Jul 22 '21 at 06:09
