This is an example simulation of an election on a 2-dimensional political spectrum (such as the Political Compass, Nolan chart, Pournelle chart, etc.) The voters are the blue dots, and candidates are the red dots, and voters support the candidates who are most similar to them ideologically (nearest distance).
 
There are 3000 voters (black dots), 3 candidates (colored dots), and voters vote honestly, supporting the candidates who are most similar to them ideologically (nearest distance).
* C, a partisan candidate, wins under [[First Past the Post electoral system|first-past-the-post voting]], since A and B split the votes of the left wing of the electorate.
 
* A, another partisan candidate, wins under [[Instant-runoff voting|Instant-Runoff Voting]] ("Ranked-Choice Voting"), after B is eliminated for not having enough first-preference votes, leaving A and C (and A is slightly closer to the center, so more people in the center support A over C).
* B, a moderate candidate, and the best representative of the average voter, wins under [[Score Voting]] (with normalized ballots), as they are the highest-rated overall by the voters. B also wins under [[Condorcet method|Condorcet methods]], as B would beat both A and C in head-to-head elections.
