place image inside grid using d3js

I want to place images inside each grid according to the data object using d3.js. here using the data each square is rendered into a grid using the d3js library. the problem here is that the image is not showing inside each grid, but it is rendering correctly inside each appropriate grid. you can find the current result and expected result below in the images. here is the code:

var data = [
    [{
        "x": 1,
        "y": 1,
        "width": 400,
        "height": 400,
        "image": "https://lh3.googleusercontent.com/wAPeTvxh_EwOisF8kMR2L2eOrIOzjfA5AjE28W5asyfGeH85glwrO6zyqL71dCC26R63chADTO7DLOjnqRoXXOAB8t2f4C3QnU6o0BA"
    }, {
        "x": 401,
        "y": 1,
        "width": 400,
        "height": 400,
        "image": "https://lh3.googleusercontent.com/Skyrdo9OUfXzZ-1N-jdhGbmpkx6G7r9QYfA3p6EKhb0u9ES4cZD9Z9C92BxM3A9VyLgHJHB7ALTPOlIfJxVLrpzYrLzPIUZsQX9mD4U"
    }],
    [{
        "x": 1,
        "y": 401,
        "width": 400,
        "height": 400,
        "image": "https://lh3.googleusercontent.com/0cDOOJjp8pUGDDFLqHFITEi35uMGZ5wHpZ9KTKridxk71kpR9MfeydpQqG5n8Mvetvkg5iVuZGeL2xMvxgBY_UL-T9p0x_Eo4EAh"
    }, {
        "x": 401,
        "y": 401,
        "width": 400,
        "height": 400,

    }]
]
var grid = d3
    .select("#grid")
    .append("svg")
    .attr("width", "1350px")
    .attr("height", "1350px");

var row = grid
    .selectAll(".row")
    .data(data)
    .enter()
    .append("g")
    .attr("class", "row");

var column = row
    .selectAll(".square")
    .data(function(d) {
        return d;
    })
    .enter()
    .append("rect")
    .attr("class", "square")
    .attr("x", function(d) {
        return d.x;
    })
    .attr("y", function(d) {
        return d.y;
    })
    .attr("width", function(d) {
        return d.width;
    })
    .attr("height", function(d) {
        return d.height;
    })
    .style("fill", "#fff")
    .style("stroke", "#222")
    .attr("transform", "translate(50,50)scale(0.5)")
    .append("svg:image")
    .attr("xlink:href", function(d) {
        return d.image;
    })
    .attr("width", function(d) {
        return d.width;
    })
    .attr("height", function(d) {
        return d.height;
    });

var grid = d3
    .select("#grid")
    .append("svg")
    .attr("width", "1350px")
