What happened?

Having an "AttributeError: module 'dask.array' has no attribute 'lib' " error, using the "graphing" module to create a histogram chart for data exploration.

What did you expect to happen?

I expected to be able to create a histogram that helps me understand my data better.

Minimal Complete Verifiable Example

```Python import pandas !wget https://raw.githubusercontent.com/MicrosoftDocs/mslearn-introduction-to-machine-learning/main/graphing.py !wget https://raw.githubusercontent.com/MicrosoftDocs/mslearn-introduction-to-machine-learning/main/Data/snow_objects.csv

Import the data from the .csv file

dataset = pandas.read_csv('snow_objects.csv', delimiter="\t")

having a look at the data

dataset import graphing # custom graphing code.

Plot a histogram with counts for each label

graphing.multiple_histogram(dataset, label_x="label", label_group="label", title="Label distribution") ```

MVCE confirmation

• [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
• [ ] Complete example — the example is self-contained, including all data and the text of any traceback.
• [ ] Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
• [X] New issue — a search of GitHub Issues suggests this is not a duplicate.
