<｜begin▁of▁sentence｜>### Instruction:
While editing a tutorial on data visualization using Python's networkx library, you notice that the background color of a plot is not visually appealing. You decide to use the CairoPlot library to customize the background color to light blue for an Erdos-Renyi graph with 10 nodes and 20 edges.
### Response:
from igraph import Graph
from igraph.drawing import Plot
from igraph.drawing.colors import color_name_to_rgb

# Create a graph
g = Graph.Erdos_Renyi(n=10, m=20)

# Create a Plot object with a specified background color
plot = Plot('graph_with_background.png', bgcolor=color_name_to_rgb('lightblue'))

# Plot the graph
plot.add(g)
plot.show()
