Description

Currently the image is just sine line, which could trick users in thinking that `plot` is for lines and `scatter` is for markers.

Research direction

Start by locating the cheatsheet source and the image for “Basic plots - plot”; the issue does not name a file or test. Compare the current sine-line illustration with the proposed marker example, and consider the work done when the image clearly shows that plot can represent markers as well as lines.
