I need to have a circular progress bar which I can use to show a user what percent they got in a test. Ideally, there would be some fixed HTML and then change the value in the JavaScript or jQuery. They could look like any of the circles below.

Thank you in advance.

var svg ;

function drawProgress(end){ 
d3.select("svg").remove() 
  if(svg){
  svg.selectAll("*").remove();
  
}
var wrapper = document.getElementById('radialprogress');
var start = 0;
 
var colours = {
  fill: '#FF0000',
  track: '#555555',
  text: '#00C0FF',
  stroke: '#FFFFFF',
}

var radius = 80;
var border = 12;
var strokeSpacing = 4;
var endAngle = Math.PI * 2;
var formatText = d3.format('.0%');
var boxSize = radius * 2;
var count = end;
var progress = start;
var step = end < start ? -0.01 : 0.01;

//Define the circle
var circle = d3.svg.arc()
  .startAngle(0)
  .innerRadius(radius)
  .outerRadius(radius - border);

//setup SVG wrapper
svg = d3.select(wrapper)
  .append('svg')
  .attr('width', boxSize)
  .attr('height', boxSize);

  
// ADD Group container
var g = svg.append('g')
  .attr('transform', 'translate(' + boxSize / 2 + ',' + boxSize / 2 + ')');

//Setup track
var track = g.append('g').attr('class', 'radial-progress');
track.append('path')
  .attr('fill', colours.track)
  .attr('stroke', colours.stroke)
  .attr('stroke-width', strokeSpacing + 'px')
  .attr('d', circle.endAngle(endAngle));

//Add colour fill
var value = track.append('path')
  .attr('fill', colours.fill)
  .attr('stroke', colours.stroke)
  .attr('stroke-width', strokeSpacing + 'px');

//Add text value
var numberText = track.append('text')
  .attr('fill', colours.text)
  .attr('text-anchor', 'middle')
  .attr('dy', '.5rem'); 

  //update position of endAngle
  value.attr('d', circle.endAngle(endAngle * end));
  //update text value
  numberText.text(formatText(end));
  
}

$('#submitClick').click(function(){
  var val = parseInt($('#percent').val());
   drawProgress(val/100)
})
 
drawProgress(10/100)

Using canvas. Change the percent for changing the angle.

var canvas = document.getElementById("cvs");
canvas.width = innerWidth;
canvas.height = innerHeight;
var ctx = canvas.getContext("2d");

var percent = 90;

ctx.beginPath();
ctx.arc(innerWidth/2, innerHeight/2, 100, 0, Math.PI * 2);
ctx.strokeStyle = "#111";
ctx.lineWidth = 20;
ctx.stroke();
ctx.closePath();

var angle = percent/100 * 360;
ctx.beginPath();
ctx.arc(innerWidth/2, innerHeight/2, 100, -90 * Math.PI/180, (angle - 90) * Math.PI/180);
ctx.strokeStyle = "#fff";
ctx.lineWidth = 20;
ctx.stroke();
ctx.closePath();

ctx.textBaseline = "middle";
ctx.textAlign = "center";
ctx.font = "40px arial bold";
ctx.fillStyle = "#fff"
ctx.fillText(percent + "%", innerWidth/2, innerHeight/2);

body {
  overflow: hidden;
  background: #000;
}

<body>
  <canvas id="cvs"></canvas>
</body>
