Can we order from bottom to top: High-Value, High to Low-Value, Lapsed High-Value? And I would think Lapsed should be red and High to Low should be yellow, though I would change once the color palette across all the visualizations is finalized.
These should be the Sankeys showing the snapshot of the same population across two weeks (not a single week snapshot), so the high-value inflows should == the outflows.
Let's also decrease the height of these.
