  1. Daytime (ah-ah-ah)

    Fighter of the Nighttime (ah-ah-ah)

    Angle of the Sun! (ah-ah-ah)

    You’re a Master of latitudes

    And data

    For Everyone

  2. For any given latitude, the length of its horizontal line covered by the moving shape describes the sun’s angle range above and below the horizon in 24h. But good gods that took me long.

  3. Thanks for the post. I’ve watched the loop a bunch of times to wrap my head around this. I understand the concept and see it in practice but it does a good job showing a visual representation of the earth tilting.

  4. Cool graphic, but took me a couple minutes of staring to fully comprehend. I think there are probably better ways of conveying this data.

  5. Created using ggplot in R using data I generated with the suncalc package. It was animated with ffmpeg.

  6. Neat! I’m curious how the area changes if the center shape, whether the amount of sunlight is globally constant over a year or not.

  7. It’s a really good representation. Folks are complaining about it not being clear. However, it is very well represented. Brought back my celestial navigation from my sailing days. The rational horizon, azimuth and declination for calculating position from celestial objects. We still used sextant once month atleast to plot position and it used be as close as 100 metres in the middle of Atlantic, which is quite good for sextant.

  8. Interesting. Where geographically is this?

    Edit: I think my question is, how exactly does the left y axis work?

  9. This is one of the most stunningly beautiful graphic I’ve ever seen on this sub.

    Great job!

  10. The visual representation of what I check the weather for – fewer sun lit hours!! Love this graph.

  11. Way cool and well-timed post, given summer equinox earlier this week! I stared at the 45°N line the first time through, really cool to see equator and the extremes. Easy to interpret visualization that just keeps giving.

  12. I have no idea what I’m looking at. I’m sure it’s clever, but IMHO not intuitive and therefore not an example of data being beautiful.

  13. So maybe this is stupid, but I’ve always wondered if the angle of UV rays affects their intensity.
