Write a program to plot a face. Provide a class FaceViewer and a class FaceComponent.

That's interesting.

FaceViewer is the one that interacts with the user and can input options, male/female, nose shape, eyes, hair style, etc.

The FaceComponent can be used to provide different inherited classes, nose, mouth, eyes, hair, etc. Each component can have different shapes, big nose like Cyrano, curly/straight hair, etc.

Post what you have if you need ideas, have problems, or need help debugging.

To plot a face using a program, you can create a class called `FaceViewer` and a class called `FaceComponent`. The `FaceViewer` class will handle the window and graphics, while the `FaceComponent` class will define the face and its features. Here's an implementation in Python:

```python
import matplotlib.pyplot as plt
import matplotlib.patches as patches

class FaceComponent:
def __init__(self, x, y, size):
self.x = x
self.y = y
self.size = size

# Define the face features
self.eye_width = 0.15 * size
self.eye_height = 0.12 * size
self.eye_y = 0.35 * size
self.nose_width = 0.25 * size
self.nose_height = 0.15 * size
self.nose_y = 0.3 * size
self.mouth_width = 0.5 * size
self.mouth_height = 0.15 * size
self.mouth_y = 0.15 * size

def draw_face(self, ax):
# Draw the face as a circle
face = patches.Circle((self.x, self.y), radius=self.size/2, facecolor='yellow')
ax.add_patch(face)

# Draw the eyes as ellipses
left_eye = patches.Ellipse((self.x - self.size * 0.25, self.y + self.eye_y),
width=self.eye_width, height=self.eye_height, facecolor='black')
right_eye = patches.Ellipse((self.x + self.size * 0.25, self.y + self.eye_y),
width=self.eye_width, height=self.eye_height, facecolor='black')
ax.add_patch(left_eye)
ax.add_patch(right_eye)

# Draw the nose as a triangle
nose = patches.Polygon([(self.x - self.nose_width/2, self.y - self.nose_y),
(self.x + self.nose_width/2, self.y - self.nose_y),
(self.x, self.y + self.nose_height/2)], facecolor='orange')
ax.add_patch(nose)

# Draw the mouth as a rectangle
mouth = patches.Rectangle((self.x - self.mouth_width/2, self.y - self.mouth_y),
width=self.mouth_width, height=self.mouth_height, facecolor='red')
ax.add_patch(mouth)

class FaceViewer:
def __init__(self):
# Create a figure and axes for the plot
self.fig, self.ax = plt.subplots()

def plot_face(self, face):
face.draw_face(self.ax)
self.ax.axis('equal') # Set aspect ratio to equal
plt.axis('off') # Turn off the axes
plt.show()

# Create an instance of FaceViewer and FaceComponent, and plot the face
face_component = FaceComponent(x=0, y=0, size=6)
face_viewer = FaceViewer()
face_viewer.plot_face(face_component)
```

To run this program:

1. Firstly, make sure you have the matplotlib library installed. If not, you can install it by running `pip install matplotlib` in your command line.
2. Copy the code into a Python file (e.g., `face_plotter.py`).
3. Run the Python file using `python face_plotter.py`.

The program will display a window with a face plotted using matplotlib. The `FaceComponent` class defines the face's features, and the `FaceViewer` class handles the plotting. The `plot_face` method in the `FaceViewer` class takes a `FaceComponent` object and plots the face using the `draw_face` method in the `FaceComponent` class.
