Strait of Hormuz — vessel charts (CSV)

Data from strait_of_hormuz_vessels_mar2026.csv (sanctioned / shadow / all rest). Gold dotted vertical lines mark Trump’s deadlines: 23 Mar (1st), 6 Apr (2nd), and 20 Apr (3rd) (x-axis extends through 21 Apr). Use the tabs to switch views: stacked bar with report link, three faceted lines, or the 2×2 facet grid.

Faceted lines — same y-axis for each series

Three panels (small multiples): one line per risk segment. Vertical scale is shared () so you can compare levels across sanctioned, shadow, and all rest on a common axis. X-axis runs from the first date in the CSV through 21 Apr (third deadline on 20 Apr). Gold dotted lines: 23 Mar (1st), 6 Apr (2nd), and 20 Apr (3rd).

Facet grid (2×2) — four series, common y-axis

Like facet_wrap / facet_grid in R: one line chart per series in a 2×2 layout. All four panels share the same vertical scale () so you can compare magnitude across sanctioned, shadow, all rest, and total vessels. Gold dotted lines: 23 Mar, 6 Apr, and 20 Apr.

Chart source: Kpler Risk and Compliance (MarineTraffic); facet panels include total vessels computed as the sum of the three published series for each day.
