The keys in the dictionary represent the nodes, while the values(lists) represent nodes of neighbors of the key. This is an undirected unweighted graph.
Is there some function to implement this in networkx or some network analysis or graph-related libraries?

Answer
You can use the nx.Graph constructor — it will add additional nodes if they don’t appear as keys in the original dictionary (data represents the dictionary in the original question):
import networkx as nx graph = nx.Graph(data)
