Explanation:

Displacement is the vector quantity that defines distance and direction between two positions.

Displacement talks about distance covered in a specified direction. Displacement is example of vector quantity because "it specifies direction" compare to distance that doesn't. Vector quantity is a quantity that has both magnitude and direction. Therefore anytime displacement is being calculated, the direction of movement of the body has to be specified e.g A body moves 8m in the direction is N45°E. That N45°E serves as the direction.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.
