Apologies - the goal is not confusion and this generally looks better when a voter is only looking at the people on their own ballot. I posted the full state to learn from the discussion.

On the axis - we made this video a few years ago. We wanted to avoid the bias of using predefined axis as setting them in advance supposes that you know those are the most important dimensions and we wanted the data to determine the dimensions. Not claiming it is perfect, but that was the rationale for our approach.

So we let the algorithm determine which issues most differentiate voters - and those turned out to be economic (taxes, opportunity, spending) - and those make up the x axis. And then which issues next differentiated voters - and those turned out to be (individual rights, foreign policy, education, immigration) - and those make up the y axis.
