According to this Github issue this was supposed to work about 5 years ago
from graphviz import Graph
hw = Graph('hello', format='svg')
hw.edge('Hello', 'World')
import panel as pn
pn.extension()
pn.Row(hw)
But it only displays a text representation of the graph. Panel version is 0.14.4. Jupyter Lab displays the graph just fine.
Anyone have any ideas on how to make this work? Your help is appreciated.
