Q:

How to move points in an orthogonal map?

I am trying to add red points at certain geolocations on the following map created by Mike Bostock. https://bl.ocks.org/mbostock/3795040. My points show up but don't move with the map. How do I edit the code to make the points move with the map. Thank you.
//add circles to svg
svg.selectAll("circle")
    .data([wr,pt,sd,jp,fm])
    .enter()
    .append("circle")
    .attr("cx", function (d) { console.log(projection(d)); return projection(d)[0]; })
    .attr("cy", function (d) { return projection(d)[1]; })
    .attr("r", "8px")
    .attr("fill", "red");

The following is what the above array being referenced.
//points
var wr = [32.6130007, -83.624201];
var pt = [48.9334357, 8.961208];
var sd = [32.715738, -117.1610838];
var jp = [35.6894875, 139.6917064];
var fm = [39.1137602, -76.7267773];

A:

You have to include the circles in the mousemove function:
svg.on("mousemove", function() {
    var p = d3.mouse(this);
    projection.rotate([λ(p[0]), φ(p[1])]);
    svg.selectAll("path").attr("d", path);

    //change the circles' positions here:
    svg.selectAll("circle").attr("cx", function(d) {
            console.log(projection(d));
            return projection(d)[0];
        })
        .attr("cy", function(d) {
            return projection(d)[1];
        })
});

PS: Some circles appear to move wrongly: they are correct, though. The thing is that they are behind the globe. To hide those circles you'll have to write another function (which is outside the scope of this answer). 
An alternative to hide the circles behind the globe is using a path instead a circle. That way, the projection will automatically clip those paths. Have a look: https://bl.ocks.org/anonymous/9e640195e2c021cd79b5ca9b2238a44c/1c43719a7d6a85d0226cf3c468ac23e570add22d
