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.

Research direction
Start by reviewing issue #34 to understand the current state of sankey support. Then examine the d3 sankey library source to understand how dropoffs could be added. The main files to modify would be the sankey chart components in the react vis source. Check comments on this issue for any additional context.
