An interactive web application that visualizes the movements and events of naval vessels during World War II. The project aims to track all ships from all navies throughout the entire war, providing comprehensive naval history visualization.

Current coverage: Imperial Japanese Navy battleships in 1945 — Yamato, Nagato, Ise, Haruna, and Hyuga — including Operation Kita and Operation Ten-Ichi-Go. Coverage will expand to more ships, navies, and years over time.

Highlights

• Scrub or play an interactive timeline and watch ships move along interpolated paths
• Campaign view for the strategic picture; Operation view for tactical detail
• Typed event markers (air, surface, submarine, sinking, and more) with nearby events clustered together
• Ship and operation search, per-ship filters, and a fading trail window to cut clutter
• Light/dark interface themes, switchable map tiles, and a selectable display time zone
