I have spent over a day trying to get my square profile images to be round in the Tree graph Im creating. Here is a fiddle that demonstrates my problem. I have commented around the code that should allow me to do what I want.

var data = [
{
"name": "Jules",
"parent": "null",

"parent": "Jules",

]
},

}
]
}
];

var root = data[0];
root.x0 = height / 2;
root.y0 = 0;
var update = function(source) {
// Compute the new tree layout.
var nodes = tree.nodes(root).reverse(),

// Normalize for fixed Depth

I had two issues, one was fixed by the answer below. The other, make sure that your URL location for the clippath is correct.
My graph was suppose to be displaying on /graph/1 so the code should be
.attr("clip-path", "url(" + document.location.pathname + "#clip-circle)");
