Default Projection Parameters

Have you ever wondered why your map was not centred to your coordinates?

The reason might be that you’re not setting scale and translate and they use the defaults.

// for example for naturalEarth
var projection = d3.geoNaturalEarth1();

projection.center()
// center = [0,0]

projections.translate()
// translate = [480,250]

projections.scale()
// scale = 175.295

The parameters are different for each projection.
