`svg-world-map` returns a [virtual-dom](https://github.com/Matt-Esch/virtual-dom#dom-model) `` node. You can either stringify it into a file or embed it into your Frontend stack.

Note that because shapes of all countries are quite a lot of data, this module weighs **roughly `43k`** when [browserified](http://browserify.org), [minified](https://github.com/mishoo/UglifyJS2#uglifyjs-2) and gzipped.

The data is from [world.geo.json](https://github.com/johan/world.geo.json).

## Installing

```shell

npm install svg-world-map

```

## Usage

```js

const map = require('svg-world-map')

const stringify = require('virtual-dom-stringify')

const myMap = map(81.8, 28.4) // Nepal

process.stdout.write(stringify(myMap))

```

## API

```

map(longitude, latitude, [opt])

```

`opt` is optional and has the following default values:

```js

const defaults = {

	ocean: '#8df', // color of the ocean

	land: 'white', // color of the land

	mapWidth: 500, // width of the ``

	pin, // virtual dom node with the pin

	pinHeight: 8 // relative to map viewBox

}

```

## Contributing

`npm test` is a regression test: It compares the generated output, to a `example/berlin.svg`, which has been manually checked by me. If you introduce a change that changes the output, *check it manually* and commit it as `example/berlin.svg`.
