I had previous asked this question https://stackoverflow.com/questions/63918432/curved-edges-in-networkx on how to achieve curved edges in networkX. It was working fine with my previous data, but when I updated the data and the code I'm unsure where I'm going wrong. The edges are only curving for certain nodes, and actually adding connections twice. I don't know why it's drawing the edges twice, once in a straight line and once curved.
My code:
import matplotlib.pyplot as plt
import networkx as nx
G = nx.Graph()
G.add_edge("Ted", "May", weight=0.5)
G.add_edge("Ted", "Ray", weight=1)
G.add_edge("Ted", "Chris", weight=1)
G.add_edge("Ted", "Sam", weight=3)
G.add_edge("Ted", "April", weight=1)
G.add_edge("Ted", "Ana", weight=0)
G.add_edge("Ana", "Ryan", weight=1)
G.add_edge("Ana", "Jim", weight=0.5)
G.add_edge("Ana", "Ben", weight=1)
for0 = [(u, v) for (u, v, d) in G.edges(data=True) if d["weight"] == 0]
for05 = [(u, v) for (u, v, d) in G.edges(data=True) if d["weight"] == 0.5]
for1 = [(u, v) for (u, v, d) in G.edges(data=True) if d["weight"] == 1]
for15 = [(u, v) for (u, v, d) in G.edges(data=True) if d["weight"] == 1.5]
for3 = [(u, v) for (u, v, d) in G.edges(data=True) if d["weight"] == 3]
pos = nx.circular_layout(G) # positions for all nodes
ax=plt.gca()
# nodes
sc = nx.draw_networkx_nodes(G, pos, node_size=700)
# edges
nx.draw_networkx_edges(G, pos, edgelist=for0, width=0)
nx.draw_networkx_edges(G, pos, edgelist=for05, width=0.5)
nx.draw_networkx_edges(G, pos, edgelist=for1, width=1)
nx.draw_networkx_edges(G, pos, edgelist=for15, width=1.5)
nx.draw_networkx_edges(G, pos, edgelist=for3, width=3)
for edge in G.edges():
source, target = edge
rad = 0.2
arrowprops=dict(arrowstyle="-",
color='blue',
connectionstyle=f"arc3,rad={rad}",
linestyle= '-',
alpha=0.6,)
ax.annotate("",
xy=pos[source],
xytext=pos[target],
arrowprops=arrowprops
)
# labels
nx.draw_networkx_labels(G, pos, font_size=20, font_family="sans-serif")
plt.show()
