# Analytics Map Enhancements

## Issues Fixed

### 1. **Top Cut Off Issue**
- **Problem**: The map was cutting off the top portion of countries
- **Solution**: 
  - Adjusted `projectionConfig.scale` from 145 to 150
  - Added `center: [0, 20]` to shift the view slightly down
  - Increased default height from 320px to 400px for better visibility
  - Added proper responsive sizing with `width: 800` and `style={{ width: '100%', height: 'auto' }}`

### 2. **Countries Not Clickable**
- **Problem**: Countries appeared interactive but didn't have click functionality
- **Solution**:
  - Added `onCountryClick` prop to component interface
  - Implemented click handler in Geography component
  - Added proper cursor styling: `cursor: 'pointer'` for countries with data
  - Countries without data show default cursor

### 3. **Country Border Visibility**
- **Problem**: Country borders were barely visible with thin white strokes
- **Solution**:
  - Changed from white outline to visible gray borders: `#CBD5E0` (light mode) / `#4A5568` (dark mode)
  - Increased stroke width from 0.5 to 0.7 for better visibility
  - Added hover state with thicker borders (1.5) and club secondary color
  - Borders now clearly define country boundaries

### 4. **Club Colors Integration**
- **Problem**: Map used generic blue colors instead of club branding
- **Solution**:
  - Integrated `useClubTheme()` hook from ClubThemeContext
  - Map gradient now uses club primary and accent colors
  - Hover borders use club secondary color
  - Color interpolation maintains accessibility while using brand colors
  - Intelligently selects colors based on brightness to ensure visibility

## New Features

### Interactive Countries
- Countries with visitor data now have:
  - Pointer cursor on hover
  - Visible border highlight in club secondary color
  - Brightened fill color on hover (+30 RGB values)
  - Click functionality (optional callback)

### Enhanced Visual Feedback
- **Hover State**: Countries brighten and show thicker borders
- **Color Borders**: All countries have visible gray borders
- **Responsive Design**: Map scales properly to container width
- **Club Branding**: Uses club's primary, secondary, and accent colors

## Component Props

```typescript
type VisitorCountriesMapProps = {
  title?: string;                    // Map title (default: "Mapa návštěvníků podle země")
  metrics: CountryDatum[];           // Country visitor data
  isLoading?: boolean;               // Loading state
  height?: number;                   // Map height in pixels (default: 400)
  onCountryClick?: (                 // Optional click handler
    countryCode: string,
    countryName: string,
    value: number
  ) => void;
};
```

## Usage Example

```tsx
import VisitorCountriesMap from '../../components/admin/VisitorCountriesMap';

<VisitorCountriesMap
  metrics={countryMapData}
  isLoading={loading}
  onCountryClick={(code, name, visits) => {
    console.log(`${name} (${code}): ${visits} visits`);
    // Handle country click - e.g., filter data by country
  }}
/>
```

## Technical Details

### Color System
- **Default Fill**: Light gray for countries without data
- **Start Fill**: Club primary color (or secondary if primary is too light)
- **End Fill**: Club accent color (or secondary in dark mode)
- **Borders**: Gray in default state, club secondary color on hover

### Responsiveness
- Map uses fixed internal width (800px) with percentage-based container width
- Maintains aspect ratio with `height: 'auto'`
- Overflow hidden prevents any layout issues

### Accessibility
- Proper cursor feedback for interactive elements
- High contrast borders for better visibility
- Color system respects dark/light mode
- Hover states provide clear visual feedback
