node colores not showing when code is imported into another jupyter notebook

[joseberlines]

I have a function like this:

def graph_of_claims(claims): ... ... return graphwidget

when this function is run in a jupyter notebook with voila the nodes appear with the corresponding color

but:

when I import that function into another jupyter notebook
from pyutils import graph_of_claims as mygraph

and run voila the graph is shown without colours.

some idea?

I was investigating this issue a bit an realised the following.

in the first case, i.e. the graph in a jupyter notebook visualised with voila the colors of the nodes are taken by the browser:

if claim['category'] == 'method':
g.setNode(claim['id'], style="fill: #f77")
if claim['category'] == 'apparatus':
g.setNode(claim['id'], style="fill: #7f7")
if claim['category'] == 'use':
g.setNode(claim['id'], style="fill: #7f7")

so when using inspector in google chrome the colors #f77, #7f7, #7f7 are to be seen.

This is not the case when importing a .py file containing the ipydagred3 into another jupyter. colors don't appear and indeed when inspecting the node elements the colors are all the same for all the nodes.
