Does anyone know how to put newline in the label of the node? \n is not working - instead some new nodes appear.
This works for me as documented:
digraph {
n[label="two\nlines"]
"on\nthree\nlines"
}
(https://dreampuf.github.io/GraphvizOnline/?engine=dot#digraph%20%7B%0D%0A%20%20%20%20n%5Blabel%3D%22two%5Cnlines%22%5D%0D%0A%20%20%20%20%22on%5Cnthree%5Cnlines%22%0D%0A%7D)
Either put in in a label
attribute (my preference), or use it as the node's name, but always enclose it with double quotes.
