Hi,

I'm experimenting with process mining in a Databricks notebook using the OSS library PM4PY. I've been working through some tutorials and the notebook they provide on Github:

https://github.com/pm4py/pm4py-core/blob/release/notebooks/3_process_discovery.ipynb

I've installed all dependencies (I think) and the below code runs in a cell with no errors but I don't see the actual image:

import pandas as pd
import pm4py
import graphviz
df = pm4py.format_dataframe(pd.read_csv('/dbfs/FileStore/shared_uploads/[username]/testfile-1.csv', sep=';'), case_id='case_id',activity_key='activity',
                             timestamp_key='timestamp')
bpmn_model = pm4py.discover_bpmn_inductive(df)
pm4py.view_bpmn(bpmn_model)

It uses graphviz for display, I'm presuming that its output might not be supported in DBX notebooks. I've seen some similar(ish) problems but not found a solution. Any thoughts/help?
