D3 fills a form with an image using a drawing

I am trying to create a circular avatar with D3.js, but I cannot make its image appear in my circle. I use svg pattern def to try to fill the circle with an image.

Can someone tell me what I'm doing wrong below? Thank.

var config = {
    "avatar_size" : 48
}

var body = d3.select("body");

var svg = body.append("svg")
        .attr("width", 500)
        .attr("height", 500);

var defs = svg.append('svg:defs');

defs.append("svg:pattern")
    .attr("id", "grump_avatar")
    .attr("width", config.avatar_size)
    .attr("height", config.avatar_size)
    .attr("patternUnits", "userSpaceOnUse")
    .append("svg:image")
    .attr("xlink:href", 'images/avatars/avatar_grumpy.png')
    .attr("width", config.avatar_size)
    .attr("height", config.avatar_size)
    .attr("x", 0)
    .attr("y", 0);

var circle = svg.append("circle")
        .attr("cx", config.avatar_size)
        .attr("cy", config.avatar_size)
        .attr("r", config.avatar_size)
        .style("fill", "#fff")
        .style("fill", "#grump_avatar");

Fill is a style property; you must use CSS notation url()to refer to a template element.

Once you fix this, you will find that you also have the wrong size, unless you intend to have four copies of the avatar laid out in a circle!

P.S. , :

var config = {
    "avatar_size" : 48
}

var body = d3.select("body");

var svg = body.append("svg")
        .attr("width", 500)
        .attr("height", 500);

var defs = svg.append('svg:defs');

defs.append("svg:pattern")
    .attr("id", "grump_avatar")
    .attr("width", config.avatar_size)
    .attr("height", config.avatar_size)
    .attr("patternUnits", "userSpaceOnUse")
    .append("svg:image")
    .attr("xlink:href", 'http://placekitten.com/g/48/48')
    .attr("width", config.avatar_size)
    .attr("height", config.avatar_size)
    .attr("x", 0)
    .attr("y", 0);

var circle = svg.append("circle")
        .attr("cx", config.avatar_size/2)
        .attr("cy", config.avatar_size/2)
        .attr("r", config.avatar_size/2)
        .style("fill", "#fff")
        .style("fill", "url(#grump_avatar)");
