In SVG (contrasted with HTML), you will want to use <image> instead of <img> for elements.

Try changing your last block with:

var imgs = svg.selectAll("image").data([0]);
            imgs.enter()
            .append("svg:image")
            ...

 var svg = d3.select("body")
        .append("svg")
        .style("width", 200)
        .style("height", 100)

I do not know why, but the image should not be duplicated, tripled, etc ... should remove the previous one and load it again but with another rotation data. This is my code:

data.csv enter image description here

d3.csv("data/data.csv").then(function(data){
//console.log(data);
// Clean data
formattedData = data.map(function(id){
id.rot_1 = +id.rot_1;
        id.trans_1 = +id.trans_1;
        return id;
});
// First run of the visualization
update(formattedData[0]);})

$("#play-button")
.on("click", function(){
    var button = $(this);
    if (button.text() == "Play"){
        button.text("Pause");
        interval = setInterval(step, 1000);            
    }
    else {
        button.text("Play");
        clearInterval(interval);
    }})

function step(){
// At the end of our data, loop back
time = (time < 76) ? time+1 : 0
update(formattedData[time]); }

function update(data) {
// Standard transition time for the visualization
var t = d3.transition()
    .duration(1000);

//console.log(d3.selectAll(data));    
//console.log(data)

// original
var imgs1 = g.append("image") // en vez de g es svg
.attr("xlink:href", "img/picturetest.png");

// EXIT old elements not present in new data.
imgs1.exit()
    .attr("class", "exit")
    .selectAll("svg:image")
    .remove();

//console.log(data)

// ENTER new elements present in new data.
imgs1.enter()
    .append("svg:image") // svg:image
    //.attr("xlink:href", "img/picturetest.png")
    .attr("class", "enter")
    .merge(imgs1)
    .transition(t)
        .attr("x", 0) // 150
        .attr("y", 0) // 80
        .attr("width", 200)
        .attr("height", 200)
        .attr("transform", "rotate("+data.rot_1+") translate("+data.trans_1+")" ); }`

My team also wanted to add images inside d3-drawn circles, and came up with the following (fiddle):
