I probably should use more!
Right now our main go-to visualizations are Freeform Tables, Line Graphs, and Summary Number/Change; then to a lesser degree Donut or Stacked Bar/Column.
We do use Funnels, but more and more I am asked by business to create the funnels as freeform tables (with the same sequential logic) so that they can compare how the funnels are trending over time.... so basically I have to make the steps (this THEN that THEN something else), and do all the % calculations between steps, etc, so that the breakdown can be by week (and we can look at last X weeks, and see how the traffic and % vary over time).
In fact, I wouldn't be surprised if they stopped looking at the funnel completely
I have also started using the new "Key Metric Summary" as well (as a replacement for paired Summary Number / Change components).
Then of course I use Text components to add change notes and table of contents for long reports.
