• The center of the board is obtained by the coordinate C(X,Y) where:
  • X = CENTER_X and
  • Y = CENTER_Y
• The coordinate "O" represents the board's orgin O(X,Y), where:
  • X=oBoard.style.left and
  • Y=oBoard.style.top
• The "x" dots represent the radius for each circle and are provided by the aRadians array.
