Including a code block and a figure

Here is a code block that is parsed from a python file:

.. literalinclude:: ../code/sinewave.py
   :language: python

Which is the result of:

```{eval-rst}
.. literalinclude:: sinewave.py
   :language: python
```

We can toggle the code block by nesting it inside a toggle directive:

```{toggle}
```{eval-rst}
.. literalinclude:: sinewave.py
   :language: python
```

Note the single `-triplet at the end of the toggle.

```{eval-rst}
.. literalinclude:: ../code/sinewave.py
   :language: python
```

The Python file saves the figure, so we can include it using the regular markdown recipe:

---
name: sine_wave
---
A sine wave

---
name: cosine_wave
---
A cosine wave
