<｜begin▁of▁sentence｜>### Instruction:
Assuming you have a complete undirected graph with 5 nodes, and you are using a custom GraphArtist class that can be used to plot this graph, how would you calculate the limits on the x/y axes such that all nodes and their labels fit within the canvas including a padding?
### Response:
from matplotlib.artist import Artist
from networkx import nx

# Assuming GraphArtist is a class defined within a graphical plotting library
# And GraphArtist.get_datalim is a method used to get the data limits for the axes

class GraphArtist(Artist):
    def get_datalim(self, graph):
        # Assuming 'graph' is a networkx Graph object and layout is precomputed
        layout = nx.spring_layout(graph)
        data = [pos for pos in layout.values()]
        x_values, y_values = zip(*data)
        padding = 0.1
        x_lim = (min(x_values) - padding, max(x_values) + padding)
        y_lim = (min(y_values) - padding, max(y_values) + padding)
        return x_lim, y_lim

# Example usage
G = nx.complete_graph(5)
artist = GraphArtist()
x_lim, y_lim = artist.get_datalim(G)
print('X-axis limits:', x_lim)
print('Y-axis limits:', y_lim)
