Cool Charts

🎨 Cool Charts

Create stunning, interactive data visualizations that transform complex data into engaging visual stories.

Quick Start

Choose your visualization type based on your data and story:

1. Network Graph - Explore relationships and discover patterns
2. Timeline - Show progression and temporal patterns
3. Dashboard - Combine multiple charts for comprehensive insights
4. Animated Story - Create cinematic tours through your data

Workflow

1. Choose Chart Type

For relationship exploration: Use force-directed network graph

• Best when: Discovering connections, seeing network structure
• Supports: Interactive filtering, physics simulation, hover details

For temporal analysis: Use timeline visualization

• Best when: Showing progression, tracking patterns over time
• Supports: Phases, duration bars, quote integration, relationship flows

For multi-metric analysis: Use dashboard with multiple chart types

• Best when: Comprehensive overview, comparing multiple dimensions
• Supports: 17+ chart types including bubble, waterfall, sankey, radar

For presentations: Add cinematic animation

• Best when: Telling a story, highlighting key moments
• Supports: Scene-based animation, particle effects, dramatic transitions

2. Prepare Your Data

Structure data as embedded JSON in the HTML file:

const DATA = {
    entities: [/* people, orgs, themes */],
    relationships: [/* connections between entities */],
    quotes: [/* supporting quotes with context */],
    timeline: [/* chronological events */]
};

See references/data-structures.md for complete schemas.

3. Implement Visualization

For quick implementation: Start with template from assets/

For custom implementation:

1. Load D3.js v7+ from CDN
2. Embed your data as JavaScript constant
3. Create SVG container with proper dimensions
4. Implement chart using patterns from references/chart-types.md
5. Add interactivity (hover, click, filters)
6. Style using design system from references/

4. Customize and Enhance

Visual polish: Apply design system (vibrant or minimalist) Interactivity: Add filters, tooltips, animations Layout: Follow spacing guidelines to prevent overlap Performance: Optimize for smooth interaction (<200 nodes)

See references/layout-patterns.md for detailed positioning guidance.

Available Chart Types

• Gantt Chart - Task duration and dependencies
• Radial Timeline - Circular time progression

Comparative Visualizations

• Bubble Chart - Multi-dimensional comparison (size, position, color)
• Radar Chart - Multi-axis skill/dimension analysis
• Parallel Coordinates - Multi-metric comparison across categories
• Heatmap - Performance matrix with color intensity

Flow Visualizations

• Sankey Diagram - Flow between stages with proportional width

Dashboard Components

• Metrics Dashboard - KPI cards with key statistics
• Geographic Map - Location-based footprint visualization

Key Features

Quote Integration

Position quotes on timeline with hover tooltips showing:

• Speaker and context
• Full quote text (truncated at 300 chars)
• Sentiment and certainty indicators
• Confidence badges

See references/chart-types.md for implementation details.

Relationship Labels

Add semantic labels to edges (e.g., "WORKED AT", "FOLLOWED", "EXEMPLIFIES")

• Positioned at curve midpoint
• Background for readability
• Hover highlighting

Animations

Edge animations: Dashed lines with moving offset for loyalty patterns Cinematic mode: Scene-based storytelling with:

• Particle explosions (50-120 particles)
• Zoom effects (1.5x to 3x scale)
• Shake and glow effects
• Sequential highlighting
• Captions and progress tracking

Design Systems

Vibrant: Gradients, shadows, colorful backgrounds, rounded corners Minimalist: Clean lines, subtle borders, uppercase labels, muted palette

Implementation Checklist

Initial Setup

• Load D3.js library (v7+)
• Embed full JSON data
• Set up SVG container with proper dimensions
• Define color schemes
• Create CSS styles

Core Visualization

• Transform data into appropriate format
• Render primary visual elements
• Add labels and legends
• Implement hover/click interactions

Enhancement

• Add filters and controls
• Integrate quotes (if applicable)
• Configure animations
• Test responsive behavior

Quality Assurance

• Verify all interactive elements work
• Test on different screen sizes
• Check z-index layering
• Validate data mapping
• Export functionality

Best Practices

1. Embed data - Don't rely on external JSON files for production
2. Use improved layout defaults - Follow layout-patterns.md for clean visuals
3. Verify positioning - Test with console.log before finalizing
4. Provide legend - Always include legend for node types and confidence
5. Consider mobile - Complex visualizations work better on desktop
6. Optimize performance - Limit to <200 nodes for smooth interaction
7. Enable export - Provide SVG export for sharing/printing
