Try this way.

node.on("click", function(d) {
  var size = d.weight * 2 + 12;
  d3.select(this).select("circle").remove();
  d3.select(this).append("rect")
    .attr("x", -(size / 2))
    .attr("y", -(size / 2))
    .attr("height", size)
    .attr("width", size)
    .style("fill", function(d) {
      return color(1 / d.rating);
    });
});

You've updated the dom elements, but not the array used by the force layout algorithm, so do this as the last line in the on click function:

graph.nodes = svg.selectAll(".node");

(You might also find without a data key function that random nodes get changed to rectangles rather than the one you clicked)
