**Exercise:** Plot the previous figure again, and see what font sizes have changed. Look up any other element of `rcParams`, change its value, and check the effect on the figure. If you find yourself making the same customizations in several notebooks, you can put changes to `rcParams` in a `matplotlibrc` file, [which...

Note that `seaborn-paper`, `seaborn-talk` and `seaborn-poster` are particularly intended to prepare versions of a figure with text sizes and other features that work well in papers, talks, and posters.To use any of these style sheets, run `plt.style.use` like this:```plt.style.use('fivethirtyeight')``` The style sheet ...

You can use it like this:```plt.style.use('./az-paper-twocol.mplstyle')```The prefix `./` tells Matplotlib to look for the file in the current directory.

To plot this rectangle, we'll use a feature we have not seen before: `Polygon`, which is provided by Matplotlib.To create a `Polygon`, we have to put the coordinates in an array with `x` values in the first column and `y` values in the second column.
