Whenever a colon(:) occurs in the value field of any of the
attributes, pydot throws an error. Please someone fix this as soon as
possible.
It is very likely to have ":" in the value provided to the URL
attribute. In my case I tried to create a node with URL='http://
www.google.com' but unfortunately this does not work. If I remove the
colon i.e give URL='http//
www.google.com', it works without any error
but that doesn't serve the purpose. So it needs to be handled.
