- 24px gaps - Consistent spacing between panels
- Chart.js/D3.js - Interactive, animated visualizations
- Real-time updates - Live data synchronization
Panel Purposes:
- Completion Rate - Phase-by-phase progress tracking (horizontal bars)
- Velocity Trend - Weekly productivity analysis (line chart with trend)
- Burndown Chart - Sprint progress vs. ideal (dual-line comparison)
- Priority Distribution - Task urgency breakdown (stacked bar)
Export Features:
- PDF generation with all 4 charts

8.2 Implementation Prompt - Analytics Dashboard
Prompt for AI/Developer:
Create an analytics dashboard with 4 chart panels showing project insights.
LAYOUT:
- Container: 2×2 grid (same as Portfolio Overview)
- Gap: 24px between panels
- Responsive: Stack vertically on mobile (<768px)
- Chart library: Use Chart.js or D3.js for visualizations
PANEL 1: COMPLETION RATE BY PHASE (Bar Chart)
Data:
- X-axis: Phase names (Phase 0, Phase 0.5, Phase 1, Dashboard 2.0, Phase 2, Phase 3)
- Y-axis: Completion percentage (0-100%)
- Bars: Horizontal bars, green gradient fill
- Labels: Show percentage at end of each bar
Visual:
- Bar color: Linear gradient (var(--status-green) to lighter green)
- Height: 40px per bar
- Padding: 8px between bars
- Font: 14px for phase names, 16px bold for percentages
- Empty bars: Gray background (var(--gray-300))
Calculation:
- completion_rate = (complete_count / total_count) * 100
- Round to nearest integer
Interaction:
- Click bar: Navigate to that phase's task list
- Hover: Show tooltip with exact counts (e.g., "415 of 530 tasks complete")
PANEL 2: VELOCITY TREND (Line Chart)
Data:
- X-axis: Week numbers (W1, W2, ..., W8) - last 8 weeks
- Y-axis: Tasks completed per week (0-120)
- Line: Blue line connecting data points
- Points: Blue circles at each data point
Visual:
- Line color: var(--primary-blue)
- Line width: 2px
- Point radius: 6px
- Grid lines: Horizontal dashed gray lines (var(--gray-300))
- Fill: Optional gradient fill under line (blue to transparent)
Calculation:
- Group tasks by week of completion (use completed_at timestamp)
- Count tasks per week
- Calculate trend: Linear regression for slope (increasing/decreasing)
- Show trend indicator: ▲ +15% or ▼ -8%
Interaction:
- Hover point: Show tooltip with exact count + week dates
- Click point: Show list of tasks completed that week
- Trend line: Show predicted future velocity (dashed line)
PANEL 3: BURNDOWN CHART (Line Chart with Ideal Line)
Data:
- X-axis: Weeks (W1 to projected end)
- Y-axis: Tasks remaining (530 down to 0)
- Ideal line: Straight diagonal from start to target end
- Actual line: Current progress
Visual:
- Ideal line: Dashed gray line (var(--gray-500))
- Actual line: Solid blue line (var(--primary-blue))
- Start point: 530 tasks (project start date)
- Current point: 115 tasks remaining (today)
- End point: 0 tasks (predicted completion date)
Calculation:
- ideal_slope = total_tasks / total_weeks
- actual_slope = tasks_completed / weeks_elapsed
- predicted_end = today + (remaining_tasks / actual_velocity)
- status: On track if actual >= ideal, Behind if actual < ideal
Status Indicator:
- On track: ✅ Green text
- Behind: ⚠️ Yellow text
- Ahead: 🎯 Blue text
Interaction:
- Hover: Show tooltip with date + tasks remaining
- Click: Show detailed burndown data table
PANEL 4: TASK DISTRIBUTION BY PRIORITY (Horizontal Bar Chart)
Data:
- Categories: P0, P1, P2, P3
- Values: Task count for each priority
- Colors: P0 red, P1 orange, P2 yellow, P3 gray
Visual:
- Bars: Horizontal, stacked in single column
- Colors: Use priority color variables
- Labels: Show count + priority name (e.g., "P0 (Critical) 23 tasks")
- Width: Proportional to percentage of total
Calculation:
- Sort by priority (P0 first)
- Calculate percentage: (count / total) * 100
- Bar width: percentage * container_width
Interaction:
- Click bar: Navigate to task list filtered by that priority
- Hover: Show tooltip with percentage
EXPORT FUNCTIONALITY:
Button: [Export PDF] in top-right corner
- Generate PDF with all 4 charts

- File name: analytics-report-{date}.pdf
DATE RANGE FILTER:
Dropdown options:
- Last 7 days
- Last 30 days (default)
- Last 90 days
- Custom range (date picker)
Behavior:
- Change: Re-fetch data with new date range, update all charts
- Animation: Smooth transition for data changes (300ms)
PROJECT FILTER:
Dropdown options:
- All 46 projects (default)
- Core (3 projects)
- Cloud (4 projects)
- By individual project
Behavior:
- Change: Re-calculate metrics for selected projects, update charts
- Multiple selection: Allow multi-select with checkboxes
DATA SOURCE:
- Fetch from data/dashboard-metrics.json
- Calculate metrics from tasks.json and project-plan.json
- Group by week: Use completed_at timestamps
- Cache: Cache calculations for 5 minutes
ACCESSIBILITY:
- Keyboard: Tab through chart panels, Enter to interact
- ARIA: aria-label for charts, describe data patterns for screen readers
- Focus: Visible outline on chart panels
- Alternative: Provide data table view for screen reader users
RESPONSIVE:
Desktop (≥1024px): 2×2 grid
Tablet (768px-1023px): 2×2 grid, smaller fonts
Mobile (<768px): 1 column stack, reduce chart height
PERFORMANCE:
- Lazy load: Only render charts when Analytics tab active
- Debounce: Debounce filter changes (300ms)
- Virtualize: Use canvas rendering for large datasets (>1000 points)
