Mushrooms are very interesting. Let's import a dataset to study them:
```python
import pandas as pd
import matplotlib.pyplot as plt
mushrooms = pd.read_csv('../../data/mushrooms.csv')
mushrooms.head()
```r
mushrooms = read.csv('../../data/mushrooms.csv')
head(mushrooms)
```

Right away, you notice that all the data is textual. You will have to convert this data to be able to use it in a chart. Most of the data, in fact, is represented as an object:
```python
print(mushrooms.select_dtypes(["object"]).columns)
```r
names(mushrooms)
```
The output is:
```output

Now that you know how to group your data and then display it as a pie or donut, you can explore other types of charts. Try a waffle chart, which is just a different way of exploring quantity.
## Waffles!
A 'waffle' type chart is a different way to visualize quantities as a 2D array of squares. Try visualizing the different quantities of mushroom cap colors in this dataset. To do this, you need to install a helper library called [PyWaffle](https://pypi.org/project/pywaffle/) and use Matplotlib:
