Let's suppose the number of lines of force produced by an object is directly proportional to its mass, so..

n=k*m

where n is the number of lines of force produced by the mass m and k is a constant.

Now assume the density of the lines at any given point in space represents the strength of the gravitational field at that point. So at a distance r from the object the density of the lines of force is..

n/(surface area of the sphere of radius r)

which is n/(4*pir^2)=km/(4*pir^2)=Gm/(r^2)

where G=k/4*pi is a constant.
