"""Creates graphs of ancestor or descendant artifacts from given one
Parameters
----------
artifact_id : int
Artifact ID to get graph for
direction : {'ancestors', 'descendants'}
What direction to get the graph in
Returns
-------
dict of lists of tuples
A dictionary containing the edge list representation of the graph,

-----
Nodes are identified by the corresponding Artifact ID.
