+```python
+ax.text(0.5, 1.01, 'computed title', transform=ax.transAxes)
+```
 - This can demand a lot of memory since it uses [`ArtistAnimation`](https://matplotlib.org/api/_as_gen/matplotlib.animation.ArtistAnimation.html) under the hood. This means that all artists are saved to memory before the animation is constructed.
 - This is a black box. If you want to understand how matplotlib animations work, using this library may hinder you. If you want to be an expert matplotlib user, you may want to pass on this library.
