Overview

TODO: Position nodes that are on both the right and left wings in the middle?

TODO: If nodes are called by the focal node as well as other nodes, ensure that they are positioned in a column based on their depth from the focal.

Butterfly flow visualization.

This represents a Sankey Flow Graph that can have a focal node. The focal node is rendered in the middle and the nodes following into it are rendered on the left and the nodes flowing out of it are rendered on the right. The user can select a new node to be the focal by clicking on it. Only the depth_of_field levels of input and output nodes are rendered to keep the graph comprehensible for large graphs.
