#112It's beautiful, but... I'm confused by the role of the play button. Can somebody explain how it works? I click on it and seemingly random things happen.
Turn on your sound. There is voice over narration.

#113This is weirdly beautiful, like the maps of undersea internet cables that frequently come up here as well. You can clearly see: 1) oil flowing out of the Persian Gulf from the Middle East to China 2) ships waiting to get through the Panama and Suez Canals 3) why people talk about “shipping lanes”. There are some obvious tracks everyone follows, because it’s the cheapest way from A to B (e.g. cape of good hope to stra…

Apparently, the current US administration thinks international law does not exist, no matter the latitude/longitude.

#114Is there a ship globe, too?

#117This is mesmerising!
Really well made and enjoyed the audio explanation.
It's a shame that it includes the now-mandatory discussion of how this shipping is actually bad because of carbon emissions. Seems to me the widespread availability of cheaper goods has been a great thing for humanity on balance!

#118In the North Atlantic most paths are slightly curved to take the most efficient route (taking curvature of the earth into account). There is one prevalent route from Gibraltar to Florida that is straight as an arrow though. What is up with that?

#119The time-based zoom interaction is clever - slowing down time as you zoom in makes the data feel more tangible. I've been working on a similar real-time globe visualization and learned a few things the hard way:
1. Throttling updates is critical. We went from per-event updates to 5-10 second batches and cut our WebSocket costs by 90%+ while the UX barely changed.
2. For the "ships crossing land" artifacts people are noticing - interpolating between sparse data points on a Mercator projection will always create these. On a globe (orthographic), great circle interpolation looks correct, but on flat maps you need to detect ocean crossings and handle them specially.
3. The biggest perf win was hybrid rendering: static heatmap for historical data + WebGL particles only for "live" movement. Trying to animate everything kills mobile.
Would love to see this with more recent data. The 2012 snapshot is fascinating but comparing pre/post-Suez blockage or COVID disruptions would be incredible.

#120Fascinating, but the dataset is obviously incomplete – there's barely any traffic in Europe until mid april. January-march looks as if there's been a zombie apocalypse.
