Any suggestions for the best way to visualize the data
once we have it? Are there some existing LIMN graphs that would be well-suited for a
funnel analysis like this one? Or should we simply use a standard line graph as we do for
other descriptive metrics studies?
Limn doesn't have many graph types but it might have a decent one for this purpose:

So you could have Step 1, Step 2, Step 3, ... on your X axis, then the number of people
who made it through each step on your Y axis.
For a better funnel visualization, we should really support Sankey diagrams:

+1, this might be overkill for a linear funnel with a small number of nodes (where a
directed graph visualization, a line chart or an actual “funnel” [1] could do the job). I
agree Sankey diagrams would be nice to have down the line for more complex scenarios.
