Elliptic orbit in 5D Space

Plotting the equation X^2 + Y^2 + Z^2 + W^2 + V^2 = 1 in 5D space explains eccentricity in elliptical orbits rather elegantly:

Values of W and V can only range between 0 & 0.98 if X,Y & Z are assumed to be 0.1. The complete chart made roughly with convert +append, -append command:
