Fun, but definitely much harder to read and interpret than a standard line chart.

Not IMO.

I like that it's a circle, it makes complete sense.

You can do that in 2D. I think a radar plot might fit well here.

I love it. I wish I could tilt the chart on the other axis at times and it could be less "thick" so its easier to read overlaps. But so far so good. My partner and I had a lot of fun exporting the city we used to live in vs where we are now.

Nice! The visualization makes it easy to compare when cities are in the same hemisphere. It would be cool if there was an option to align the seasons when comparing cities in different hemispheres.
