# matplotlib.

For quick plotting, you can't go wrong with matplotlib.

**Notes**

To be able to use the tools in these videos you'll need to install them first.

```
python -m pip install numpy matplotlib
```

From here, to get "hello world" running for matplotlib, just run;

```
import numpy as np
import matplotlib.pylab as plt
x = np.linspace(0, 1, 100)
y = x ** 2
plt.plot(x, y);
```
