npm install --save svgmap
```
```javascript

import 'svgmap/dist/svgMap.min.css';
```
### CDN
```html

## Usage
Create an HTML element where to show your map, then use JavaScript to initialize:
```html
```
```javascript
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:

## Attribution
If you need more detailed maps or more options for your data, there is a great open source project called [datawrapper](https://github.com/datawrapper/datawrapper) out there, with a lot more power than svgMap.
svgMap uses [svg-pan-zoom](https://github.com/bumbu/svg-pan-zoom) by [Anders Riutta](https://github.com/ariutta) (now maintained by [bumpu](https://github.com/bumpu)).
The country flag images are from [country-flags](https://github.com/hampusborgos/country-flags) by [Hampus Joakim Borgos](https://github.com/hampusborgos).
Most data in the demos was taken from [Wikipedia](https://www.wikipedia.org).
