rings
  Full Sail
  Trial Run
  Spyglass
  Davy Jones

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
  Boarding Parties ring: Full Sail, trend: stable
  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**.
  Smoke Screens ring: Trial Run, trend: new
  Kraken Diplomacy ring: Spyglass, trend: new
    Exploring alliances with *sea monsters*. Negotiations ongoing.

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
  Sloop ring: Full Sail, trend: up
  War Galleon ring: Trial Run, trend: up
    Captured from the Spanish fleet. Massive firepower but
    **slow to turn** — best for convoy raids, not chases.
  Longboat ring: Davy Jones, trend: down

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.
  Port Raids ring: Trial Run, trend: up
  Rival Pirates ring: Trial Run, trend: new
  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
  Fishing Villages ring: Davy Jones, trend: down
    Terrible ROI and **bad for reputation**. The parrot union
    filed a formal complaint.

Crew Welfare quadrant: bottom-right
  Grog Rations ring: Full Sail, trend: stable
    Non-negotiable. Cutting grog rations caused the *Great Mutiny of 1716*.
  Sea Shanty Program ring: Trial Run, trend: new
    Hired a shanty master. Crew productivity up **25%** during
    long voyages. Signature tune: *"Yo Ho Ho and a Bottle of Rum"*.
  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.

Overview

Technology radars visualize how an organization adopts and evaluates technologies, practices, or strategies. Inspired by the ThoughtWorks Technology Radar, each radar arranges items (“blips”) into concentric rings indicating adoption stage, grouped by quadrant categories.

Click any quadrant label to drill down into a detail view with expanded blip descriptions. Click the “Blip Legend” toggle to show or hide the numbered reference listing below the radar.

Syntax

tech-radar Title

rings
  Ring1
  Ring2

Quadrant Name quadrant: position
  Blip Name ring: RingName, trend: value
    Description text (markdown supported)

Settings

Key	Description	Default
`chart`	Must be `tech-radar`	—
`title`	Radar title	None

Rings

Rings represent adoption stages, ordered from innermost (highest commitment) to outermost (lowest). Declare them in a rings block:

rings
  Adopt
  Trial
  Assess
  Hold

You can use any ring names — the classic Adopt/Trial/Assess/Hold is common but not required.

Ring Aliases

Rings support aliases for shorter blip references:

rings
  Adopt as a
  Trial as t
  Assess as x
  Hold as h

Quadrant quadrant: top-right
  Item Name ring: a, trend: up

Quadrants

Exactly 4 quadrants are required. Each needs a unique position:

Techniques quadrant: top-right
Tools quadrant: top-left
Platforms quadrant: bottom-left
Languages quadrant: bottom-right

Positions: top-left, top-right, bottom-left, bottom-right

Custom Colors

Override the default quadrant color with color:

Tools quadrant: top-left, color: purple

Default colors: top-left=blue, top-right=green, bottom-left=red, bottom-right=orange.

Blips

Blips are items placed on the radar. Each is indented under its quadrant and requires a ring reference:

  Kubernetes ring: Adopt
  Micro Frontends ring: Trial, trend: up

Ring matching is case-insensitive — ring: adopt and ring: Adopt both work.

Trends

The optional trend metadata controls the visual indicator on each blip:

Trend	Indicator	Meaning
`new`	Double circle	Newly added to the radar
`up`	Inward crescent	Moving toward center (higher adoption)
`down`	Outward crescent	Moving away from center (declining)
`stable`	Plain circle	No change since last assessment

Omitting trend renders a plain circle (same as stable).

Descriptions

Further-indented lines below a blip become its description. Descriptions support inline markdown:

  Rust ring: Assess, trend: new
    Evaluating for **performance-critical** services.
    Key benefits: *zero-cost abstractions* and `no GC pauses`.
    - 12x throughput improvement in image pipeline
    - See [evaluation doc](https://wiki.example.com/rust)

Descriptions appear in the quadrant detail view and on hover/click in the main radar view.
