Is it possible to make some edge is directed but others are not

I’m trying to create a visualization that demonstrates the connections between nodes A and B using two types of edges. The first edge is undirected, indicating a general connection between these two nodes. The second edge is directed, signifying a specific activity or flow from node A to B. Is it possible to achieve this in the visualization?

Yes, just set the property edge_end_marker to "none" for the edges that should appear as undirected.
