<canvas id="canvas" width="1024" height="600"></canvas>

<script type="text/JavaScript">   

// void ctx.arc(x, y, radius, startAngle, endAngle, anticlockwise);

var ctx = document.getElementById('canvas').getContext('2d');
  
 for (var i = 0; i < 7; i++) {
  for (var j = 0; j < 7; j++) {
    var r = Math.floor((Math.random() * 256));
    var g = Math.floor((Math.random() * 256));
    var b = Math.floor((Math.random() * 256)); 
    ctx.strokeStyle = 'rgb(' + r + ',' + g + ', ' + b + ')';
    ctx.beginPath();
    ctx.arc(10 + j * 25, 10 + i * 25, 10, 0, Math.PI * 2, true);
    ctx.stroke();
  }
}
