@dkkoval/react-eu-stats-map

A React component for visualizing data on a map of Europe by country. This package makes it easy to present regional data visually, providing a choropleth map representation of European countries.

Features

• Display a map of Europe with individual countries colored based on provided data.
• Supports tooltip interactions to display additional information about each country.
• Easy integration with responsive container components to make the map adjust to the size of the parent.

Installation

To install the package, use npm or yarn:

npm install @dkkoval/react-eu-stats-map

or

yarn add @dkkoval/react-eu-stats-map

Usage

Here is an example of how to use the EUMap component in a React application.

Example

import populationJson from './population.json';
import EUMap, { getCountryCode, CountryCode } from '@dkkoval/react-eu-stats-map';

// Assuming the json file has title and value name
interface StatsData {
  title: string;
  valueName: string;
  data: {
    [region: CountryCode]: number;
  };
}

// Helper function to convert region names to country codes
function transformDataKeys(data: Record<string, number>): Record<CountryCode, number> {
  const transformedData: Partial<Record<CountryCode, number>> = {};

  Object.entries(data).forEach(([key, value]) => {
    const code = getCountryCode(key);
    if (code) {
      transformedData[code] = value;
    }
  });

  return transformedData as Record<CountryCode, number>;
}

function App() {
  const { data: rawData, title, valueName }: StatsData = populationJson;

  const data = transformDataKeys(rawData);

  return (
    <div className='App' style={{
      width: '90vw',
      height: '90vh',
      border: '1px solid #eee',
      display: 'flex',
      justifyContent: 'center',
      alignItems: 'center',
      margin: '24px',
    }}>
      <EUMap
        width={800}
        height={500}
        title={title}
        valueName={valueName}
        data={data}
      />
    </div>
  );
}

export default App;

Props

• width: The width of the map (number).
• height: The height of the map (number).
• title: A string to display as the map title.
• valueName: The unit or type of data being visualized (e.g., "millions people").
• data: An object representing the values to display for each country, where the keys are country codes and values are numerical data.

Country Codes

The data prop should use country codenames as keys to identify different regions. The country codes used are:

Helper Functions

• getCountryCode(name: string): CountryCode | undefined: Converts a string representing the country name into the corresponding country code. This function is useful for transforming user-provided or external data to match the required format.
