Description

In order to visualize the lost data/money/visitors, we should be able to show "dropoffs" on the sankey diagram (Google Analytics has a great example). Current d3-sankey does not support this behavior. Most likely we'll have to fork/adjust it.

This task should be implemented after #34.

Contributor guide

Research direction
Investigate the d3 sankey source code to understand how links and nodes are rendered, and explore how to add arbitrary 'dropoff' nodes or links to represent lost flow. Consider using a modified version or a custom wrapper.
