How do we draw electric field lines for a negative charge in a vacuum?

[ehabmozart]

Suppose we have two charges in vacuum. They are positive and negative. If we want to draw the electric field lines around the negative charge. Do we draw the lines inward (negative) or outward (field lines produced by the +ve on -ve). I remember that free body diagram on a bidy does not include forces produced by the body itself but the forces applied on it.. What about in this situation? . Thanks to whoever responds!
