## Usage

``` javascript
var datasets = require( '@stdlib/datasets' );
```

#### datasets( name\[, options\] )

Returns standard library datasets.

``` javascript
var data = datasets( 'MONTH_NAMES_EN' );
/* returns
    [
        'January',
        'February',
        'March',
        'April',
        'May',
        'June',
        'July',
        'August',
        'September',
        'October',
        'November',
        'December'
    ]
*/
```

The function forwards provided `options` to the dataset interface specified by `name`. 

``` javascript
var opts = {
    'data': 'cities'
};

var data = datasets( 'MINARD_NAPOLEONS_MARCH', opts );
/* returns
    [
        {'lon': 24,'lat': 55,'city': 'Kowno',
        {'lon': 25.3,'lat': 54.7,'city': 'Wilna',
