Comparison Table Generator

Comparison Table Generator

Overview

This skill generates interactive comparison table MicroSims that allow students to compare multiple items across several criteria. Each table includes color-coded star ratings, difficulty/​category badges, logos, hover tooltips with descriptions, and a responsive design. The output follows the microsim-standardization skill standards including proper index.md documentation, metadata.json with Dublin Core elements, and mkdocs.yml navigation updates.

When to Use This Skill

Use this skill when:

• Creating educational comparisons (e.g., programming languages, frameworks, tools, distributions)
• Building decision-making aids with multiple criteria
• Presenting rated comparisons with visual indicators
• Need interactive tables with hover tooltips for additional context

Workflow

Step 1: Gather Requirements

Ask the user for the following information:

1. Table Title: The main title for the comparison (e.g., "Linux Distribution Comparison")
2. MicroSim Name: Kebab-case directory name (e.g., linux-distro-comparison)
3. Items to Compare: List of 3-8 items with:
   • Item name
   • Logo filename (SVG preferred, 32x32px)
   • Tooltip description (1-2 sentences)
4. Rating Columns: 1-4 rating criteria (each rated 1-5 stars)
5. Difficulty/​Category Column: Optional column with Easy/​Medium/​Hard badges (or custom categories)
6. Description Column: Text column header (e.g., "Best For", "Use Case")
7. Legend Items: Descriptions for difficulty badges

Step 2: Create Directory Structure

Create the MicroSim directory at docs/​sims/[microsim-name]/ with:

docs/​sims/[microsim-name]/
├── index.md          # Documentation page
├── main.html         # Interactive comparison table
├── style.css         # Styling with star colors, badges, tooltips
├── metadata.json     # Dublin Core metadata
└── logos/            # SVG logo files for each item
    ├── item1.svg
    ├── item2.svg
    └── ...

Step 3: Generate main.html

Use the template in assets/​main-template.html as the base. Key customization points:

1. Title: Update the <title> and <h2> elements
2. Table Headers: Customize the <thead> columns
3. Table Rows: For each item, create a <tr> with:
   • data-tooltip attribute containing the item description
   • Logo + name cell using .distro-cell class
   • Rating cells with appropriate star counts and color classes
   • Difficulty badge with appropriate class (easy/​medium/​hard)
   • Description text cell
4. Legend: Update legend badges to match the difficulty column categories

Star Rating Pattern:

<!-- 4 out of 5 stars (yellow-green) -->
<td class="rating">
    <span class="stars stars-4">★★★★</​span>
    <span class="stars-empty">★</​span>
</​td>

Star color classes:

• stars-5: Green (#22c55e) - Excellent
• stars-4: Yellow-green (#84cc16) - Very Good
• stars-3: Orange (#f59e0b) - Good/​Average
• stars-2: Red-orange (#f97316) - Below Average
• stars-1: Red (#ef4444) - Poor

First Row Note: The first row's tooltip automatically appears BELOW instead of above to avoid being hidden by the header.

Step 4: Generate style.css

Copy the template from assets/​style-template.css. The CSS includes:

• Star rating color system (5-color scale)
• Difficulty badge styling (easy/​medium/​hard)
• Pure CSS hover tooltips with smooth transitions
• First-row tooltip fix (displays below instead of above)
• Responsive design for mobile/​tablet
• Consistent row heights for logo alignment

Customization may be needed for:

• Custom badge categories (beyond easy/​medium/​hard)
• Custom color schemes
• Additional column types

Step 5: Create index.md

Use the template in assets/​index-template.md to create documentation that includes:

1. YAML Frontmatter: title, description, quality_score
2. Title: Level 1 header matching the table title
3. Iframe: Embedded view of main.html
4. Fullscreen Button: Link to view main.html fullscreen
5. About Section: Explanation of the comparison
6. Rating Explanations: What each rating criterion measures
7. Item Summaries: Brief description of each compared item
8. Learning Objectives: Bloom's Taxonomy-aligned objectives

Step 6: Create metadata.json

Create Dublin Core metadata following the schema in assets/​metadata-schema.json:

{
  "title": "Comparison Table Title",
  "description": "Interactive comparison table showing...",
  "creator": "Author Name",
  "date": "YYYY-MM-DD",
  "subject": ["comparison", "keyword1", "keyword2"],
  "type": "Interactive Simulation",
  "format": "text/​html",
  "language": "en-US",
  "rights": "CC BY 4.0",
  "educationalLevel": "High School",
  "learningResourceType": "comparison table",
  "library": "CSS (no JavaScript library)"
}

Step 7: Add Logo Files

Place SVG logo files in the logos/ subdirectory:

• Recommended size: 32x32px
• SVG format preferred for scalability
• Name files with kebab-case matching item names (e.g., debian.svg, arch-linux.svg)

If logos are not provided, prompt the user to:

1. Provide logo files to copy
2. Provide URLs to download logos from
3. Create simple placeholder SVG icons

Step 8: Update mkdocs.yml Navigation

Add the new MicroSim to the site navigation in mkdocs.yml:

1. Find the nav: section
2. Locate or create the "Simulations" or "MicroSims" section
3. Add an entry for the new comparison table:

nav:
  - Simulations:
    - Comparison Table Name: sims/​microsim-name/​index.md

Step 9: Validate and Report

After creating all files:

1. Verify all files exist in the directory
2. Validate metadata.json against the schema
3. Check that iframe height is appropriate (typically 400-600px based on row count)
4. Report the created files and their locations
5. Suggest running mkdocs serve to preview the result

Customization Options

Custom Badge Categories

To use categories other than Easy/​Medium/​Hard:

1. Add new CSS classes in style.css following the .difficulty pattern
2. Update the legend to explain the new categories
3. Use consistent color coding (green=good, yellow=neutral, red=challenging)

Custom Color Schemes

The default uses semantic colors (green=good, red=poor). To customize:

1. Modify .stars-1 through .stars-5 in style.css
2. Ensure sufficient contrast for accessibility
3. Update legend if color meanings change

Additional Column Types

The template supports:

• Rating columns: Star ratings 1-5
• Badge columns: Categorical badges with colors
• Text columns: Plain text descriptions
• Logo+Name columns: Image with text

For new column types, add appropriate CSS classes.

Notes

• Iframe Height: Calculate based on number of rows. Approximately 60px per row + 150px for header/​legend. Default 470px works for 5 rows.
• Tooltip Length: Keep tooltips under 200 characters for readability.
• Logo Consistency: Ensure all logos use the same dimensions to prevent row height shifting.
• First Row Tooltips: The CSS automatically positions the first row's tooltip below to avoid header overlap.
• Accessibility: Use semantic color coding and ensure text has sufficient contrast.
