Why is nothing being displayed on the webpage?

Question

The file "LoanStats3a.csv" is in the same folder. Yet somehow this is not working. Also I am diving the x and y values fort he lines because the amount is too large, however, this should assign them normal values.

<html>
<title>Loans</title>

<script src="http://d3js.org/d3.v3.js" charset="utf-8"></script>
<style>
    #LoanStats3a {
        color: blueviolet;
    }
</style>

<body>
    <script>
        d3.csv("LoanStats3a.csv", function (file1) {
            var bg = d3.select("body").append("svg")
                .attr("width", 5000)
                .attr("height", 5000);

            var data1 = [{
                    x: d.loan_amnt,
                    y: d.term
                },
                {
                    x: d.int_rate,
                    y: d.annual_inc
                },
                {
                    x: d.member_id,
                    y: d.id
                }
            ];

            var group = bg.append("g")
                .attr("transform", "translate (100,100)");
            var line = d3.svg.line("line")
                .x(function (d) {
                    return d.x / 100;
                })
                .y(function (d) {
                    return d.y / 100;
                });

            bg.selectAll("path")
                .data(file1)
                .enter()
                .append("line")
                .attr("cx", 500)
                .attr("cy", 500)
                .attr("d", line)
                .attr("fill", "black")
                .attr("stroke", "black")
                .attr("stroke-width", 20);
        });
    </script>

</body>

</html>

Furthermore, here is the code when I use local data and still nothing is displayed:

<html>


<title>Loans</title>

<script src="http://d3js.org/d3.v3.js" charset="utf-8"></script>

<style>
    #LoanStats3a {
        color: blueviolet;
    }
</style>

<body>
    <script>
        d3.csv("LoanStats3a.csv", function (file1) {
            var bg = d3.select("body").append("svg")
                .attr("width", 5000)
                .attr("height", 5000);

            var data1 = [
                //{x:d.loan_amnt , y : d.term},
                //{x:d.int_rate , y : d.annual_inc},
                //{x:d.member_id , y : d.id}
                {
                    x: 10,
                    y: 20
                },
                {
                    x: 30,
                    y: 40
                },
                {
                    x: 50,
                    y: 60
                }

            ];

            var group = bg.append("g")
                .attr("transform", "translate (100,100)");
            var line = d3.svg.line()
                .x(function (d) {
                    return d.x / 100;
                })
                .y(function (d) {
                    return d.y / 100;
                });

            bg.selectAll("path")
                .data([data1])
                .enter()
                .append("line")
                .attr("cx", 500)
                .attr("cy", 500)
                .attr("d", line)
                .attr("fill", "black")
                .attr("stroke", "black")
                .attr("stroke-width", 20);

        });
    </script>

Here is a solution to your problem

You are not that far off

 var svg = d3.select("body") .append("svg") .attr("width", 5000) .attr("height", 5000) .append("g") .attr("transform", "translate(100,100)"); var arc = d3.svg.arc() .innerRadius(80) .outerRadius(100) .startAngle(0) .endAngle((100 * Math.PI)-1); svg.append("path") .attr("class", "arc") .attr("d", arc);

 .arc { fill: red; }
