How to do it...

In this recipe we will project the world map using various different D3 built-in projection modes. Here is the code sample:

<script type="text/javascript"> 
    var width = 300, 
        height = 300, 
        translate = [width / 2, height / 2]; 
 
    var projections = [ // <-A 
        {name: 'geoAzimuthalEqualArea', fn: d3.geoAzimuthalEqualArea() 
                .scale(50) 
                .translate(translate)}, 
        {name: 'geoConicEquidistant', fn: d3.geoConicEquidistant()
