<｜begin▁of▁sentence｜>### Instruction:
As an Online Content Creator, imagine you're creating a tutorial on data visualization techniques for your audience. You're using Python with the NetworkX library to demonstrate plotting on a Cartesian coordinate system. In your tutorial, you want to show how to draw an ellipse at the center of the plot with specific dimensions and save it as an image file.

Here's how you might phrase it:

"Today, we're diving into Python's NetworkX library to visualize data on a Cartesian coordinate system. Let's say you're working with a dataset and want to showcase an ellipse representing certain parameters. How would you utilize the `draw` method from the `DescartesCoordinateSystem` module to plot an ellipse centered on the coordinate system, with a horizontal radius of 0.1 and a vertical radius of 0.2? And once you've created this visualization, how do you save it as an image file named 'coordinate_system_plot.png' for easy sharing and reference?"
### Response:
from igraph.drawing import Plot
