Dependencies required for visualize functionality not included in setup.py

There are dependencies required to run the visualize script that are not included as package dependencies in the setup.py

We potentially don't want to increase the package's dependency footprint massively, so if many more packages are required, we could handle it in a similar way to pandas, where it gives an informative message like this for dependencies that aren't required for the package's core operation:

>>> import pandas as pd
>>> pd.read_parquet('asdfad')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.9/site-packages/pandas/io/parquet.py", line 316, in read_parquet
    impl = get_engine(engine)
  File "/usr/local/lib/python3.9/site-packages/pandas/io/parquet.py", line 31, in get_engine
    raise ImportError(
ImportError: Unable to find a usable engine; tried using: 'pyarrow', 'fastparquet'.
A suitable version of pyarrow or fastparquet is required for parquet support.
Trying to import the above resulted in these errors:
 - Missing optional dependency 'pyarrow'. pyarrow is required for parquet support. Use pip or conda to install pyarrow.
 - Missing optional dependency 'fastparquet'. fastparquet is required for parquet support. Use pip or conda to install fastparquet.
