A highly customizable, animated roadmap timeline component built with shadcn/ui, React, Framer Motion, and Recharts. This component combines a vertical event timeline with an integrated analytics dashboard, offering a comprehensive view of project milestones and progress.

• Vertical Timeline: Expandable cards with a centered timeline, status indicators (past, current, future), and type categorization.
• Analytics Dashboard: Interactive charts including progress bars, status distribution pie, completion trends, type breakdowns, completion estimates, and event density heatmaps.
• Type Categorization: Events tagged with types (e.g., Development, Marketing) displayed as color-coded badges and summarized per period.
• Dark Theme Support: Seamlessly integrates with Next.js next-themes and custom CSS variables from global.css for light/dark mode switching.
• Dynamic Period Formatting: Supports quarterly (e.g., Q1 2025) or half-year (e.g., H1 2025) periods.
• Visual Feedback: Progress bars, checkmarks, and status-specific styling (e.g., green for past, yellow for current).
• Smooth Animations: Framer Motion powers card expansions, transitions, and progress animations.
• Exportable Data: Download analytics data as JSON with a single click.
• Customizable: Tailwind CSS with custom theme variables (--card, --chart-1, etc.) and extensible via props and data.

• React
• Framer Motion (npm install framer-motion)
• Lucide React (npm install lucide-react)
• Recharts (npm install recharts)
• Next Themes (npm install next-themes)
• shadcn/ui (Card)

• Timeline:
  • Cards expand on click with progress bars and type badges.
  • Status (past, current, future) affects styling and timeline markers.
  • Type summaries (e.g., "2 Development, 1 Marketing") appear in card headers.
• Analytics Dashboard:
  • Features filterable tabs (Overview, Types, Estimates, Density).
  • Charts are responsive but fixed at 300x200px; adjust via Recharts props if needed.
  • Data export saves as roadmap-analytics.json.
• Theme Integration:
  • Relies on next-themes with attribute="class" and your global.css variables.
  • No explicit useTheme needed; CSS variables handle light/dark switching.
• Performance: Uses useMemo for event rendering to optimize re-renders.
