ASCII Diagram Skill

Create structured diagrams using text characters — flowcharts, decision trees, tables, timelines, org charts, and more.

Diagram Types

Flowcharts

code

Decision Trees

code

                    [Frage?]
                   /        \
                 Ja          Nein
                /              \
          [Ergebnis A]    [Frage 2?]
                          /        \
                        Ja          Nein
                       /              \
                 [Ergebnis B]   [Ergebnis C]

Vertical Flow

code

  ┌──────────┐
  │ Phase 1  │
  └────┬─────┘
       │
  ┌────▼─────┐
  │ Phase 2  │
  └────┬─────┘
       │
  ┌────▼─────┐
  │ Phase 3  │
  └──────────┘

Comparison Tables

code

╔═══════════╦══════════════╦══════════════╗
║           ║  Option A    ║  Option B    ║
╠═══════════╬══════════════╬══════════════╣
║ Speed     ║  ★★★★☆      ║  ★★☆☆☆      ║
║ Cost      ║  ★★☆☆☆      ║  ★★★★★      ║
║ Quality   ║  ★★★☆☆      ║  ★★★★☆      ║
╚═══════════╩══════════════╩══════════════╝

Timelines

code

──●────────●────────●────────●────────●──
  R1       R2       R3       R4       R5
  Setup    Score    Key      Push     Final
           starts   turn            scoring

Hierarchy / Org Charts

code

              ┌─────────┐
              │  Root   │
              └────┬────┘
           ┌───────┼───────┐
      ┌────▼───┐ ┌▼────┐ ┌▼────────┐
      │ Child1 │ │ C2  │ │ Child3  │
      └────────┘ └─────┘ └─────────┘

Character Palette

Connectors: ─ │ ┌ ┐ └ ┘ ├ ┤ ┬ ┴ ┼ Double: ═ ║ ╔ ╗ ╚ ╝ ╠ ╣ ╦ ╩ ╬ Arrows: ► ◄ ▲ ▼ → ← ↑ ↓ ▶ ◀ ────► Points: ● ○ ◆ ◇ ★ ☆ Blocks: █ ▓ ▒ ░

Rules

•Always wrap in code blocks (```) for alignment
•Count characters carefully — misaligned boxes look broken
•Keep line width under 60 chars when possible (printability)
•Use consistent box sizes within one diagram
•Label arrows and connections clearly
•For complex diagrams, build top-to-bottom or left-to-right (not both)
•Test alignment by counting chars in each line
