Hi im having trouble applying the basic plot_graph example to my own dataset. I can reproduce the step matric example, but when trying to display the plot_graph, im getting the following exception
`
KeyError Traceback (most recent call last)
/opt/conda/lib/python3.7/site-packages/pandas/core/indexes/base.py in get_loc(self, key, method, tolerance)
2894 try:
-> 2895 return self._engine.get_loc(casted_key)

pandas/_libs/hashtable_class_helper.pxi in pandas._libs.hashtable.PyObjectHashTable.get_item()
KeyError: 'type'
The above exception was the direct cause of the following exception:
KeyError Traceback (most recent call last)
/opt/conda/lib/python3.7/site-packages/pandas/core/generic.py in _set_item(self, key, value)
3573 try:

2896 except KeyError as err:
-> 2897 raise KeyError(key) from err
2898
KeyError: 'type'
During handling of the above exception, another exception occurred:

Any tips on this?
