Usage

Create an HTML element where to show your map, then use JavaScript to initialize:

<div id="svgMap"></div>

new svgMap({
  targetElementID: 'svgMap',
  data: {
    data: {
      gdp: {
        name: 'GDP per capita',
        format: '{0} USD',
        thousandSeparator: ',',
        thresholdMax: 50000,
        thresholdMin: 1000
      },
      change: {
        name: 'Change to year before',
        format: '{0} %'
      }
    },
    applyData: 'gdp',
    values: {
      AF: { gdp: 587, change: 4.73 },
      AL: { gdp: 4583, change: 11.09 },
      DZ: { gdp: 4293, change: 10.01 }
      // ...
    }
  }
});

This example code creates a world map with the GDP per capita and its change to the previous year: https://stephanwagner.me/create-world-map-charts-with-svgmap#svgMapDemoGDP

To create your own translations, check out country-list by Saša Stamenković.

Attribution

If you need more detailed maps or more options for your data, there is a great open source project called datawrapper out there, with a lot more power than svgMap.

svgMap uses svg-pan-zoom by Anders Riutta (now maintained by bumpu).

The country flag images are from country-flags by Hampus Joakim Borgos.

Most data in the demos was taken from Wikipedia.
