The network diagram shows multiple rectangular nodes connected by directional arrows around a central purple node labeled “Attack Success”. Inside the central node are the values “Yes 27.6” and “No 72.4”. At the top center is a node labeled “Reporting The Incident” with values “Yes 94.1” and “No 5.94”. To its right is a node labeled “External Support” with values “Yes 95.3” and “No 4.69”. A two-headed arrow connects “Reporting The Incident” and “External Support”. At the upper left is a node labeled “Crew Response” with values “Yes 92.6” and “No 7.36”. On the left side is a node labeled “Ship Area Boarded” with values: “MainDeck 15.5”, “StoreRoom 2.37”, “EngineRoom 15.7”, “SteeringGearRoom 1.81”, “Barge 8.81”, “Accomodation 1.29”, “PoopDeck 1.63”, “Other 0.61”, and “NotBoarded 52.3”. Below it is a node labeled “Number of Pirates” with values: “OneToFour 59.1”, “FiveToTen 38.3”, and “MoreThanTen 2.61”. At the bottom left is a node labeled “Steaming or Anchoring” with values “Steaming 86.5” and “Anchoring 13.5”. At the bottom center is a node labeled “Ship Type” with values: “BulkCarrier 35.9”, “Container 5.19”, “GeneralCargo 4.85”, “Tanker 32.7”, “Tug 19.7”, and “Other 1.65”. On the upper right side is a node labeled “Naval Support” with values: “AfterIncident 25.6”, “DuringIncident 6.61”, and “NoSupport 67.8”. Below it is a node labeled “Time” with values: “MorningAfternoon 17.6”, “AfternoonEvening 15.8”, “EveningNight 22.9”, and “NightMorning 43.7”. Further down is a node labeled “Rain Intensity” with values: “Light 74.7”, “Moderate 16.2”, “Heavy 3.68”, and “VeryHeavy 5.35”. At the lower right is a node labeled “Wind” with values: “Light 36.6”, “Moderate 45.0”, and “Heavy 18.5”. Arrows from the central node point toward the surrounding nodes. Arrows also connect several surrounding nodes to each other. Arrows point from “Ship Area Boarded” to “Crew Response”, “Number of Pirates”, “Naval Support”, “Time”, “Rain Intensity”, and “Wind”. An arrow points from “Steaming or Anchoring” to “Ship Type”. An arrow points from “External Support” to “Naval Support”.Tree-augmented network of S1 under 50% scenario
