You can use clip-path property to implement this as suggested by Brad. 

node.append("circle")
  .attr("r", function(d) {
    d.radius = d.weight * 2 + 12;
    return d.radius;
  })
  .attr("class", "logo")  
  .style("fill", "transparent")
  .style("stroke", "black")
  .style("stroke-width", 0.25)
  .on("mouseover", function() {
    d3.select(this)
      .style("fill", "url(#/images/fake/FakeTree/100331934)");
  })
  .on("mouseout", function() {
    d3.select(this)
      .style("fill", "transparent");
  });

node.append("clipPath")
  .attr('id', function(d, i) {
    return "clip" + i
  })
  .append("circle")
  .attr("class", "clip-path")
  .attr("r", function(d) {
    return d.radius;
  })
  .style("fill", function(d) {
    return color(1 / d.rating);
  });

node.append("svg:image")
  .attr("class", "circle")
  .attr("xlink:href", d => d.url)
  .attr("clip-path", function(d, i) {
    return "url(#clip" + i + ")"
  })
  .attr("x", function(d) {
    return -d.radius;
  })
  .attr("y", function(d) {
    return -d.radius;
  })
  .attr("width", function(d) {
    return d.radius * 2;
  })
  .attr("height", function(d) {
    return d.radius * 2;
  });
