Wikimedia's instant-runoff 2024 board election (mbin doesn't support SVGs so I uploaded the 2560px PNGrender)
(kbin.melroy.org)
So, if I'm reading this correctly, the votes were tallied and the initial ranking was placed on the left side from most votes at the top and least votes to the bottom.
The candidate with the least votes is eliminated and then the people who voted for them either get moved to the candidate with their next highest preference or to the nebulous "nobody" at the bottom if they have no other preference remaining.
This continues with the position for some candidates changing as their total number of votes changes. Eventually the top candidate receives the minimum number of votes to qualify for a position; in this case that looks like 1/5 of the votes as their are 5 positions open.
Any further votes that would be given to them are instead passed to the next highest preferred candidate until there are only 5 candidates remaining who all qualify for the positions.
What a fantastically clear representation of a complex process!
