// Create a Paper.js Path to draw a line into it:
var hexagon = new Path();
// Color our path black
hexagon.strokeColor = 'black';

// How many points do we want our object to have
var points = 6;
// How large should it be
var radius = 60;
// 0 to 2PI is a circle, so divide that by the number of points
// in our object and that's how many radians we should put a new
// point in order to draw the shape
var angle = ((2 * Math.PI) / points);

// For as many vertices in the shape, add a point
for(i = 0; i <= points; i++) {

  // Add a new point to the object
  hexagon.add(new Point(
    // Radius * Math.cos(number of radians of the point) is the x position
    radius * Math.cos(angle * i), 
    // And the same thing with Math.sin for the y position of the point
    radius * Math.sin(angle * i)

// Offset the shape so it's fully displayed on the canvas
