Random coordinates need to move little right

I have amcharts map which shows circle on it. I have few records(nearly 200) which do not have locations. These records(circle) I am showing in the map in Sea so that those records clearly will be visible.

I have tried, but circles I need to have little space between circles and those need little right side

This is my code

result.forEach(element => {
if(element.loc=='NULL')
{     
  var r = 1000590/111300, // = 100000 meters
  y0 = 27.990741,
  x0 = 153.556045,

  u = Math.random(),
  v = Math.random(),
  w = r * Math.sqrt(u),
  t = 2.3 * Math.PI * v,
  x = w * Math.cos(t),
  y1 = w * Math.sin(t),
  x1 = x / Math.cos(y0),
  newY = y0 + y1,
  newX = x0 + x1
  element.lat=newY
  element.long=newX
}
});

This is my output

Something like this I need but little right side

How can I fix this ?
