<｜begin▁of▁sentence｜>### Instruction:
Given a graph with an edge set [(0, 1), (1, 2), (2, 3), (3, 0)], can you use igraph's DescartesCoordinateSystem to draw the graph with a Cartesian coordinate system?
### Response:
from igraph import Graph, Plot
import igraph as ig
from igraph.drawing.coord import DescartesCoordinateSystem

# Define a graph with some edges
g = Graph([(0, 1), (1, 2), (2, 3), (3, 0)])

# Create a plot with Descartes Coordinate System
plot = Plot(coordinate_system=DescartesCoordinateSystem())

# Add the graph to the plot
plot.add(g)

# Draw the graph with the Descartes Coordinate System
plot.redraw()

# Save the plot to a file
plot.save('graph_with_descartes_coords.png')
