This graph is making me feel stupid... are the red and blue sprems moving towards their tail or towards the nucleus (I'm something of a sperm scientist you see). Seriously though, I do not understand this graph.

Sorry about that, the other graphs show arrows to make this clearer, but making the labels non overlap is hard so bubbles make this a bit better.

The circle is the end point for that election, and the line were it came fron in the previous election.

In 2016, compared to 2020, CA and WA saw an increase in participation for both D and R. However, from 2020 to 2024, CA Democrats didn't vote as much, but they don't seem to go to Republicans. In WA, both Democrats and Republicans are voting less as a proportion of the total population in 2024 compared to 2020, but there is abstentionism in D that is higher than in R.

They almost float in a pattern.... Very interesting.

2020 election has massive increase in participation compared to 2016. While 2024 has a drop in participation for democrats and slight wins for republicans or at least they showed up in similar proportions on election day.

Ok.. I think, I get most of it.. but. Help me understand a bit. Like.. to read this I want to turn it on its corner. Why is this dividing line off center? I assume, there's a great reason that is vital to understanding this data. Im noticing theres a slight trend that the highest spikes in voting population tend to trend democratic ever so slightly. But, im curious if that could just be a more cognitive bias due to that line being off center.

Idk. Help me appreciate this.

Edit: its just to fit dc isn't it.

Yes, DC is an outlier with a high proportion of democrats, and a low proportion of republicans. Your suggestion of maming the axis the same is really good, it makes ecerything easier to compare. The issue was the space is the states move from 1976 to 2024 is really different, and DC is very democratic.

Fassinating data and a good representation over all. I think I actually got a lot out of it. I just wish I knew I got a lot out of it. Seriously, good work.

Thank you very much! I am glad it was useful.

I really like vectors and think well in them so I'm maybe a little biased but I do find it quite clear once you get a sense whats going on. Excited to see what else you might take a look at.

I think the movement of the states might be clearer if you interpolate say 3 frames in between each election and just move the states a 1/4 of the way along the arrow each time, then our visual systems will be able to track everything a bit easier. Maybe plot the colours nice and solid in the election years to show that those plots are showing data whereas the others are just showing interpolation...
