Overall reaction to the visualization

• Many describe it as beautiful, mesmerizing, and “interactive documentary”-like.
• The voiceover + map choreography (zooming, coloring, time-based zoom) are widely praised as a strong storytelling pattern.
• Some suggest this narrative style could be reused for photography portfolios or other explorable explainers.
• A few find the background music unnecessary or the play-button behavior confusing without sound.

Data vintage, accuracy, and technical quirks

• Data appears limited to 2012; several wish for updated datasets, especially to compare pre/post-COVID or Suez blockage.
• Users notice “ships” crossing land or continents and suspect AIS gaps, hardware issues, GPS jitter, and/or interpolation artifacts.
• AIS is explained: ships over a certain size must broadcast via VHF; shore and satellite receivers collect this, so mid-ocean data is sparse.
• Map projection and rendering raise issues: Mercator distortions, misaligned tracks near ports, and calls for a globe/orthographic version.
• Some get WebGL or “modern browser” errors; others are impressed a 2016-era JS app still runs smoothly.

Insights into global shipping patterns

• Clear visualization of major lanes: Persian Gulf–Asia oil routes, Panama and Suez chokepoints, Singapore as a hub.
• Striking absence of traffic in the Southern Ocean, Northwest Passage, Greenland, Hudson Bay, and Hudson Bay-era historical routes.
• Seasonal shutdown of cold-water northern ports is very visible; commenters note economic and supply-chain implications.
• Differences between great-circle routes and weather/current-optimized paths (e.g., North Pacific, North Atlantic) are discussed.

Climate, regulation, and future routes

• Several note that northern port seasons and Arctic routes will change with warming, potentially massively impacting container shipping via a Northeast Passage.
• IMO 2020 sulfur limits spark debate: reduced SO₂ improves health but removes some cooling; some think tradeoffs were poorly considered, others say they were understood.
• Speculation that a post-hydrocarbon world would reduce fuel shipping; some lament the obligatory carbon-emissions framing vs. benefits of cheap global goods.
