One solution is to support minmax(margins). With that method you can simply draw a histogram that indicates how many new (first preference) votes each candidate would need to win (or tie) with the winner / current leader.

- This visualization method could be useful additional information also in other methods, but it would not be as accurate.
- For detailed analyis the pairwise matrix will be important in any case. But for quick visualization histograms (= n numeric values) are something that people can generally understand based on a quick look.
- I have seen 2D graphs that show all parwise wins, e.g. in Debian. They are however quite difficult to draw automatically, and the positioning of candidates in the drawing space (e.g. higher, lower) may not be neutral (unless they are in one row or circle).
