To paraphrase, this is a simulation which places candidates and voters on a two-parameter preference space. This is useful because two dimensions are easy to visualize, but the same intuitions apply to higher-dimensional spaces.
Each point is colored to answer "which candidate wins when the popular opinion is normally distributed about this point?". That means the fractured visualization shows IRV's non-monotonicity, and how even when popular opinion is close to a centrist candidate (here in red) it might be that the voting system results in the election of an extreme candidate (green).
