`matplotlib.patches` is a module in the `matplotlib` library that provides classes for creating different types of geometrical shapes such as rectangles, circles, polygons, ellipses, etc. These shapes are used to highlight specific regions or areas in a plot or chart.
Some of the commonly used classes in the `matplotlib.patches` module are:
- `Rectangle`: A rectangular shape with given width and height.
- `Circle`: A circular shape with given radius.
- `Polygon`: A shape with given vertices.
- `Ellipse`: An oval shape with given width and height.
These classes have various methods and properties that allow customization of the shape's appearance. For example, the `Rectangle` class has methods to set the edge color, fill color, and linewidth of the rectangle. Similarly, the `Ellipse` class has methods to set the edge color, fill color, and angle of rotation.
Overall, `matplotlib.patches` provides a convenient way to add visual elements to a plot or chart, making it more informative and visually appealing.
