SVG Illustration System

This skill provides guidance for creating consistent, high-quality hand-drawn style SVG illustrations for the DevOps LMS.

Overview

The illustration system uses a hybrid approach:

1. Reusable Vue Components - For common diagram patterns
2. Design System Composable - Shared constants and utilities
3. Custom SVG - Only when no component fits (rare)

---

Available Components

1. IllustrationLinearFlow

Purpose: Sequential step-by-step processes

Best For:

• CI/CD Pipelines
• SDLC Phases
• Scrum Framework Flow
• Any A → B → C → D process

Props:

interface Props {
  steps: Array<{
    label: string      // Main text
    sublabel?: string  // Secondary text
    icon?: string      // Emoji icon
    color: string      // Tailwind color name
  }>
  direction?: 'horizontal' | 'vertical'  // Auto-determined by step count (optional)
  showFeedbackLoop?: boolean             // Show return arrow
  feedbackLabel?: string                 // Label for feedback
  size?: 'sm' | 'md' | 'lg' | 'xl' | '2xl' | '3xl' | 'full'
}

Auto-Direction (No need to specify direction):

Steps	Layout	Behavior
≤5	Horizontal	Side-by-side flow, full width
6-10	Vertical	Stacked flow, 280px width
>10	Vertical + Scroll	600px max-height with scrolling

You can still override with direction: horizontal or direction: vertical if needed.

     /________\
    /          \ ← Bottom layer (many/large) - emerald
   /______________\

Size Options

All illustration components support a size prop to control the maximum width:

Size	Max Width	Best For
sm	384px	Vertical flows, simple diagrams
md	448px	Compact horizontal flows
lg	512px	Medium checklists
xl	576px	Standard illustrations
2xl	672px	Checklists with longer text
3xl	768px	Wide comparisons
full	100%	Full-width illustrations (default for most)

Default Sizes by Component

Component	Default Size	Reasoning
IllustrationLinearFlow	Auto-sized	Direction and size determined by step count
IllustrationChecklist	2xl	Single-column lists don't need full width
IllustrationTeamComposition	full	Team cards spread horizontally
IllustrationComparisonMap	full	Side-by-side comparisons need space
IllustrationPyramid	xl	Pyramid with side descriptions needs moderate width

IllustrationLinearFlow Auto-Sizing

The component automatically determines layout and size:

• ≤5 steps: Horizontal layout, full width
• 6-10 steps: Vertical layout, 280px width
• >10 steps: Vertical layout with 600px max-height scrolling

When to Override Defaults

• Override direction only when you specifically need horizontal for >5 items or vertical for ≤5 items
• Use size: md or size: lg when you want a more compact look
• Defaults work well for most cases - only override when needed

When to Use Each Component

Decision Tree

What type of diagram do you need?
│
├── Sequential process? (A → B → C)
│   └── Use: IllustrationLinearFlow
│
├── Checklist/list with checkboxes?
│   └── Use: IllustrationChecklist
│
├── Team/roles with responsibilities?
│   └── Use: IllustrationTeamComposition
│
├── Side-by-side comparison?
│   └── Use: IllustrationComparisonMap
│
├── Pyramid/hierarchy where size shows quantity?
│   └── Use: IllustrationPyramid
│
└── None of the above?
    └── Create custom SVG (see below)

---

Creating Custom SVG (Rare Cases)

Only create custom SVG when no component fits. Follow these rules:

1. Use Design System Constants

<script setup>
import {
  COLORS,
  SPACING,
  STROKES,
  OPACITY,
  TYPOGRAPHY,
  getColor,
  getHandDrawnRotation
} from '~/composables/useIllustrationDesign'
</script>

2. Hand-Drawn Style Rules

• Dashed strokes: Use stroke-dasharray with design system patterns
• Slight rotation: Apply getHandDrawnRotation(index) for variation
• Semi-transparent fills: Use fill-opacity from OPACITY constants
• Rounded corners: Use rx attribute with SPACING.borderRadius

3. Template Structure

<template>
  <svg
    :viewBox="`0 0 ${width} ${height}`"
    class="w-full h-auto"
    role="img"
    aria-label="Descriptive label"
  >
    <!-- Elements here -->
  </svg>
</template>

4. Accessibility

• Always include role="img" and aria-label
• Use descriptive labels for screen readers
• Ensure sufficient color contrast

Integration with Lessons

In Markdown Files (MDC)

Components are automatically available in markdown via MDC syntax:

Here's how the Scrum framework flows:

::illustration-linear-flow
---
steps:
  - label: Sprint Planning
    color: violet
  - label: Daily Scrum
    color: blue
  - label: Sprint Review
    color: emerald
  - label: Retrospective
    color: amber
---
::

As you can see, Scrum is an iterative process...

In Vue Pages

Import directly from the components directory:

<script setup>
import { IllustrationLinearFlow } from '~/components/illustrations'
</script>

<template>
  <IllustrationLinearFlow :steps="mySteps" />
</template>

Quality Checklist

Before completing any illustration:

• Uses appropriate component (or justified custom SVG)
• Colors match topic semantics (e.g., emerald for success)
• Text is readable and not overlapping
• Has accessible aria-label
• Renders correctly in dark mode
• Responsive (uses w-full h-auto)
• Integrates naturally with lesson content

---

Future Components (Planned)

When these patterns are needed frequently, new components will be added:

• IllustrationTimeline - Events on a timeline
• IllustrationCycle - Circular/cyclic processes
• IllustrationHierarchy - Tree structures (parent-child relationships)
• IllustrationPillars - Supporting pillars diagram

Note: IllustrationPyramid was added to support testing pyramids and layered hierarchies.
