 Mushrooms are very interesting. Let's import a dataset to study them:

-mushrooms.head()

 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:
