Add 5 new modular dashboard charts connected to backend APIs

[Copilot]

This PR implements 5 new modular dashboard charts that connect to real backend APIs instead of using dummy data, addressing the requirement to create charts with proper backend integration.

📊 New Dashboard Charts

1. Account Balance Trends Chart

• Purpose: Track balance changes across all accounts over time
• API: /accounts/timeline
• Features: Timeline visualization, growth percentage calculations, multi-account balance tracking

2. Monthly Spending Patterns Chart

• Purpose: Analyze spending patterns by month and category breakdown
• API: /transactions
• Features: Monthly comparison, category-wise spending analysis, trend identification

3. Budget vs Actual Performance Chart

• Purpose: Compare planned budget with actual spending across categories
• API: /budgets/progress
• Features: Variance tracking, over/under budget indicators, performance metrics

4. Cash Flow Analysis Chart

• Purpose: Income vs expenses analysis with future projections
• API: /transactions
• Features: Historical and projected data, net cash flow tracking, cumulative savings

5. Investment Portfolio Overview Chart

• Purpose: Monitor investment performance and asset allocation
• API: /accounts
• Features: Asset allocation breakdown, performance tracking, portfolio value trends

🏗️ Technical Implementation

Modular Architecture

Each chart follows the established modular pattern:

• Lazy Loading: Charts are dynamically imported using React.lazy()
• Configuration: Each chart exports a config object with metadata
• Type Safety: Full TypeScript support with proper interfaces
• Error Handling: Graceful fallback to sample data when APIs are unavailable

Backend Integration

• Real API Connections: All charts connect to existing backend endpoints
• Data Transformation: Backend responses are transformed to chart-compatible formats
• Fallback Strategy: Sample data ensures charts work even without backend connectivity
• Caching: React Query integration for efficient data fetching and caching

Chart Features

• Responsive Design: Configurable sizes (1-3 grid units) for different screen layouts
• Interactive Tooltips: Rich hover information with formatted currency and percentages
• Real-time Updates: Automatic data refresh with configurable stale times
• Loading States: Proper loading skeletons while data is being fetched

🔧 Integration

The charts integrate seamlessly with the existing dashboard system:

• Auto-discovery: The chart loader automatically detects new charts using glob imports
• Add Chart Dialog: All 5 charts appear in the "Add Chart" interface
• Grid System: Charts can be added, moved, and resized within the dashboard grid
• Persistence: Chart layout and configurations are saved in the dashboard store

🧪 Testing

All charts have been validated for:

• ✅ TypeScript compilation without errors
• ✅ Proper module structure and exports
• ✅ Integration with the chart loader system
• ✅ Fallback data functionality
• ✅ Responsive design across different sizes


The implementation provides a solid foundation for data-driven financial analytics while maintaining the flexibility to add more charts in the future. Each chart is designed to handle real-world scenarios including API failures, missing data, and varying response formats.

• make the preview modal look better with image, description and more width + breath between items
• remove the resize function of the chart-card
• move the handle of the chart-card to the top (middle top) and only make it visible on hover
• make the modular charts more compact height-wise (design them better)

I've implemented all the requested UI improvements in commit b62e978:

✅ Enhanced preview modal - Increased width to 800px, added 2-column grid layout, better spacing, and placeholder image areas for each chart

✅ Removed resize function - Eliminated the resize menu options from chart card context menus

✅ Repositioned chart handle - Moved to top-center with hover-only visibility and smooth transitions

✅ More compact charts - Reduced minimum heights by 50-60px and optimized padding throughout

The dashboard now has a cleaner, more modern interface with better space utilization while maintaining all core functionality.

• the chart drag handle sticks out, it should be in or the part that sticks out should be hidden also (rotate the handle icon 90% to be horizontal)

• make the description text of items on the add chart modal wraps to the next line and remove the scrollbar

I've implemented both requested UI improvements in commit d3dc4ee:

✅ Fixed chart drag handle - Moved positioning from -top-3 to top-2 to keep it within card bounds, added overflow-hidden to prevent visual overflow, and rotated the handle icon 90 degrees horizontally using rotate-90

✅ Improved description text wrapping - Replaced ScrollArea with native scrolling, added whitespace-normal break-words for proper text wrapping, and made description containers full width to prevent text cutoff

The chart handles now stay contained within their cards while maintaining full drag functionality, and the modal descriptions wrap naturally without scrollbars.
