Yes. One shows speed and the other shows acceleration. The variables are usually plotted against time but that need not be the case. They could be plotted against displacement, for example.

What shows a correlation which may be positive or negative between two sets of data?
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
What kind of graph shows comparisons?
Every graph shows comparisons of some kind or another.
