Diagrammo — All Chart Types

Every dgmo code fence below renders a different chart type, and the prose around them shows the Markdown formatting the integration renders alongside diagrams. Edit the data to experiment! For the full editor experience visit diagrammo.app.

Markdown formatting

Diagrams live inside ordinary Markdown, so everything below renders normally next to the dgmo fences — bold, italic, ~~strikethrough~~, inline code, and links.

rings

Tactics quadrant: top-right
  Ambush at Dawn ring: Full Sail, trend: stable
    Our most reliable boarding tactic. **90% success rate** when
    approaching from the east with the sun behind us.
    - Crew morale peaks at dawn — grog hasn't worn off yet
    - Reduced cannon fire needed: *3 volleys* vs 8 at midday
    - See [battle log](https://wiki.pirates.example/dawn-ambush)
  Boarding Parties ring: Full Sail, trend: stable
    Standard 20-man teams equipped with **cutlasses**, *grappling hooks*,
    and smoke pots. Training regimen updated after the *Tortuga Incident*.
  Decoy Flags ring: Trial Run, trend: up
    Flying false colours until within cannon range. Early results
    are promising — merchant ships drop anchor **40% more often**
    when they see a Dutch East India flag.
    - Works best in *foggy conditions*
    - Risk: Royal Navy ships sometimes call the bluff
  Smoke Screens ring: Trial Run, trend: new
    Burning wet straw and tar barrels on approach. Visibility drops to
    **under 10 metres** — perfect for sneaking alongside.
  Kraken Diplomacy ring: Spyglass, trend: new
    Exploring alliances with *sea monsters*. Negotiations ongoing
    but the Kraken's demands are... unreasonable.
    - Wants **50% of all treasure** plus exclusive fishing rights
    - Communication barrier: only speaks in bubbles
  Night Raids ring: Trial Run, trend: up
    Blackened sails and muffled oars. Three successful raids on
    *sleeping harbours* this quarter. Key constraint: **no moonlight**.
  Ramming ring: Davy Jones, trend: down
    Costs more in hull repairs than it's worth. The *HMS Splinter*
    incident of 1716 proved this conclusively.

Vessels quadrant: top-left
  Brigantine ring: Full Sail, trend: stable
    Our workhorse. Fast, manoeuvrable, carries **18 cannons**.
    - Crew capacity: 100 pirates
    - Top speed: *11 knots* in fair wind
    - Draft shallow enough for **coastal ambushes**
  Sloop ring: Full Sail, trend: up
    Fastest ship in the fleet. Only **6 cannons** but can outrun
    anything the Royal Navy sends. Perfect for *reconnaissance*
    and courier runs between hideouts.
  War Galleon ring: Trial Run, trend: up
    Captured from the Spanish fleet. Massive firepower but
    **slow to turn** — best for convoy raids, not chases.
    - 42 cannons across *three gun decks*
    - Requires 200+ crew to operate effectively
    - Ongoing hull repairs from [Battle of Nassau](https://wiki.pirates.example/nassau)
  Frigate ring: Spyglass, trend: new
    Intercepted blueprints from a *British shipyard*. Could be our
    next flagship if we can find enough **seasoned carpenters**.
  Junk Rig ring: Spyglass, trend: new
    Far Eastern design with **battened sails** — easier to handle
    in storms and requires *fewer crew*. Trader Wong demonstrated
    one in Macao harbour.
  Longboat ring: Davy Jones, trend: down
    Too slow, too small, too leaky. Last three longboat missions
    ended in **catastrophic sinkings**. Retired from active duty.

Plunder Targets quadrant: bottom-left
  Merchant Convoys ring: Full Sail, trend: stable
    Core revenue stream — **78% of total plunder**. East India
    Company ships running the spice route remain most lucrative.
    - Average haul: *4,200 doubloons* per convoy
    - Best intercepted near the [Windward Passage](https://wiki.pirates.example/windward)
    - Seasonal peak: July–September during *monsoon trade runs*
  Spanish Treasure Fleets ring: Full Sail, trend: stable
    The **crown jewels** of piracy. Annual fleet carries gold,
    silver, and emeralds from the New World. Requires *coordinated
    multi-ship ambush* but one raid funds operations for a year.
  Port Raids ring: Trial Run, trend: up
    Shifting from sea-only operations. The raid on *Port-de-Paix*
    yielded **12,000 doubloons** and a warehouse of rum.
  Rival Pirates ring: Trial Run, trend: new
    Controversial but profitable. Blackbeard's crew carries
    **more gold** than most merchants. Ethics committee (the parrot)
    has filed an objection.
  Royal Treasury Ships ring: Spyglass, trend: new
    High risk, astronomical reward. Requires:
    - Inside information from *corrupt harbourmasters*
    - At least **3 allied ships** for the blockade
    - A really good escape plan
  Whaling Ships ring: Spyglass, trend: stable
    Moderate value — whale oil fetches **decent prices** in European
    markets. But the ships fight back *hard*.
  Fishing Villages ring: Davy Jones, trend: down
    Terrible ROI and **bad for reputation**. The parrot union
    filed a formal complaint. We're pirates, not bullies.

Crew Welfare quadrant: bottom-right
  Grog Rations ring: Full Sail, trend: stable
    Non-negotiable. Cutting grog rations caused the *Great Mutiny
    of 1716*. Current allocation: **2 pints per day** per pirate.
    - Premium rum reserved for post-battle celebrations
    - Watered grog for the night watch (safety first)
  Code of Conduct ring: Full Sail, trend: stable
    Our **Articles of Agreement** — fair share of plunder, compensation
    for injuries, voting rights on major decisions. *Democracy at sea.*
  Sea Shanty Program ring: Trial Run, trend: new
    Hired a shanty master from *Liverpool*. Crew productivity up
    **25%** during long voyages. Current repertoire:
    - "Yo Ho Ho and a Bottle of Rum" — *morale boost*
    - "What Shall We Do with a Drunken Sailor" — **work efficiency**
    - "Haul Away Joe" — anchor duty motivation
  Dental Plan ring: Spyglass, trend: up
    Exploring options. Most crew down to **4 teeth** on average.
    Parley with a Port Royal dentist scheduled for Q3 1718.
    - Estimated cost: *3 doubloons per extraction*
    - [Tooth census results](https://wiki.pirates.example/dental)
  Parrot Companions ring: Full Sail, trend: up
    Every pirate deserves a **shoulder companion**. Proven benefits:
    - *Scouts* that can spot sails at 3x human range
    - Morale boost: crew happiness up **30%**
    - Built-in alarm system for surprise attacks
  Retirement Fund ring: Spyglass, trend: new
    Proposal to set aside **5% of all plunder** for retirement.
    Controversial — most pirates don't expect to *live that long*.
  Plank Walking ring: Davy Jones, trend: down
    Terrible for recruitment and **crew retention**. Modern pirates
    prefer *marooning* — at least they get a pistol and a bottle.
