The `font.family` attribute in Python's Matplotlib library is used to set the font family of the text in a plot.
Here is an example code snippet that demonstrates how to use `font.family` to set the font family to 'serif':
```python
import matplotlib.pyplot as plt
plt.plot([1, 2, 3, 4], [1, 4, 9, 16])
plt.title('Example plot')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.rcParams['font.family'] = 'serif'
plt.show()
```
In this example, we first plot a simple line graph using the `plot()` function. We then set the title, x-label, and y-label using `title()`, `xlabel()`, and `ylabel()` respectively.
Finally, we set the font family to 'serif' using `font.family`. This changes the font of all the text elements in the plot to the specified font family.
Note that we use `plt.rcParams` to modify the default font family for all plots in the current session. If you only want to modify the font family for a specific plot, you can use `font.family` directly on that plot object, like this:
```python
plot = plt.plot([1, 2, 3, 4], [1, 4, 9, 16])
plot.set_title('Example plot')
plot.set_xlabel('X-axis')
plot.set_ylabel('Y-axis')
plot.set_fontfamily('serif')
plt.show()
```
In this example, we use the `set_title()`, `set_xlabel()`, and `set_ylabel()` methods to set the title and axis labels of the plot. We then use `set_fontfamily()` to set the font family to 'serif' for this specific plot object.
