[SOLVED] How to Create a network graph based a simple Datafrme

I am wondering how I can create an Edge list (from, to) based on this type of data. Both columns are inside a pandas data frame and the type is string.

Name	Co-Workers
A	A,B,C,D
B	A,B,C,D
C	A,B,C,E
D	A,B,D,E
E	C,D,E

And also I want to remove connections like AA BB CC ,....

First split the column from string to list of separate values.
Second, explode the column.
Third, create a directional graph.

Process the data by mozway code

And then:

from matplotlib.pyplot import figure
G = nx.from_pandas_edgelist(df2, source='Name', target='Co-Workers')
figure(figsize=(10, 8))
nx_graph = nx.compose(nx.DiGraph(), G)
nx.draw_shell(nx_graph, with_labels=True)

Result graph:
