Usage
import networkx as nx
from dagviz import visualize_dag
g = nx.DiGraph()
# Creates the graph to visualize
# If the graph contains cycles (i.e., not a DAG), visualization fails
g.add_nodes_from([0, 1, 2, 3, 4, 5])
g.add_edges_from([(0, 1), (0, 2), (1, 2), (1, 3), (1, 5), (2, 4), (0, 4), (2, 3)])
print(visualize_dag(g, round_angle=False))
