D3js projection EPSG code for ogr2ogr?

Question

I use d3js for vector projection, it's something such as d3.geo.mercator():

var projection = d3.geo.mercator()
        .scale(150)
        .translate([0, 0]);

I also use ogr2ogr for raster projections, it's something such as epsg:3857:

gdalwarp -of GTiff -s_srs epsg:4326 -t_srs epsg:3857 ...

As I must have the both matching perfectly...

Is there a place where we can find for each d3js projection to which EPSG projection code it must be associated ?
