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

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

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
