Smooth animation of changing Leaflet marker's position on setLatLng

// just include d3js and add animaDur in ms to marker's option

L.SVG.prototype._setPath = function(layer,path){ 
	if(layer.options.animaDur)
		d3.select(layer._path).transition().duration(layer.options.animaDur).ease('linear').attr('d',path)
	else
		layer._path.setAttribute('d', path); 
}

Correct code:

L.SVG.prototype._setPath = function (layer, path) {
      if (layer.options.animaDur) {
        d3.select(layer._path).transition().duration(layer.options.animaDur).ease(d3.easeLinear).attr('d', path);
      }
      else {
        layer._path.setAttribute('d', path);
      }
    }
