Answer:
Electric field lines can be considered similar to pressure lines where the electric potential would be similar to a voltage.
One can draw pressure lines in a hose from a positive voltage to a voltage of zero at the exit of the hose.
If one were to reverse the voltage the field lines would also be reversed.
Note: at 100 lbs force at a faucet and a hose length of 10 m one would have a force drop of 100 lbs / 10 m of 10 lbs / m in the hose.
Practically one would never have an exit force of 0 lbs or no water would flow - but one can see the similarities
