We discovered big understandings from force vs. displacement graphs and energy vs. position graphs. The area in a force vs. displacement graph is work. The work done by the spring force is - 1/2(k) (change in x)^2.
Energy depends on displacement, and a large displacement leads to a large energy. A small displacement leads to a small energy. For the kinetic energy vs. displacement graph, the total energy was constant. The difference between the total energy and the kinetic energy is the potential gravitational energy.

I forgot slopes!The slope in an energy vs. position graph is force. For the spring force vs. displacement graph the slope is the spring constant.
Who is the scribe?
