here you see the single occurences "A" and "L" in the table refer to NaN. I dont want the connection to the NaN. Is there either a way to remove the node NaN with all its edges (without hurting the other nodes) or to plot data without a target point at all?

Currently, django-postgresql-dag provides numerous methods for retrieving nodes, and a few for retrieving edges within the graph. In-progress are filters within the CTEs in order to limit the area of the graph to be searched, ability to easily export to NetworkX, and other improvements and uti...
