I’m searching for a way to change the node shapes of a holoviews network graph (e.g. into triangles or squares instead of the default circles).
Currently, I am using “.opts(node_color= …)” to change the color of the nodes, but I couln’t find a similar parameter for the node shape. Additionally, if possible, I would like to make the outline of the nodes dotted.
If anyone has any tips on how to do this, please let me know. Thanks in advance!

Also… if you want to map the property to data, looks like this works:

import numpy as np
import holoviews as hv
from holoviews import opts
import networkx as nx
hv.extension('bokeh')
opts.defaults(opts.Graph(width=400, height=400))
# Declare abstract edges
N = 8
node_indices = np.arange(N)
source = np.zeros(N)
target = node_indices
G = nx.DiGraph()
for t in target:
G.add_edge(0, t)
nx.set_node_attributes(G, {i:('square' if i<3 else 'circle') for i in target}, "node_marker")
simple_graph = hv.Graph.from_networkx(G,nx.layout.circular_layout).opts(node_marker='node_marker')
simple_graph
