To modify the outline color of a node in networkx, we can use set_edgecolor() method.
Steps
- Create a Pandas dataframe with from and to keys.
- Return a graph from Pandas DataFrame containing an edge list.
- Get the position of the nodes.
- Draw the nodes of the graph using draw_networkx_nodes().
- Set the outline color of the nodes using set_edgecolor().
- To display the figure, use show() method.
Example
from networkx import * import matplotlib.pyplot as plt import pandas as pd plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True df = pd.DataFrame({'from': ['A', 'B', 'C', 'A'], 'to': ['D', 'A', 'E', 'C']}) G = nx.from_pandas_edgelist(df, 'from', 'to') pos = spring_layout(G) nodes = draw_networkx_nodes(G, pos) nodes.set_edgecolor('red') plt.show()
