A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
linear graph between an independent and independent variable
A graph shows a proportional relationship if it is a straight line that passes through the origin (0,0). This indicates that as one variable increases, the other variable increases at a constant rate. Additionally, the ratio of the two variables remains constant throughout the graph. If the line is not straight or does not pass through the origin, the relationship is not proportional.
a graph of the independent variable and dependant that shows a graph with a fixed gradient (I.E a line graph) The equation of the graph will be given by y = mx +c where m is the gradient and c is a constant
Graphs showing the relationship (or not) between two independent variables.

If the graph shows a direct relationship, then the line will go up. If it shows an inverse relationship, the line will go down. A direct relationship means that as one variable increases, so does the other. On a graph, this means that as we move out along one axis, we also move out along the other. An inverse relationship means that as one variable increases, the other one decreases. So, for example, as we move to the right (X increasing), we have to move down (Y decreasing).

The period vs amplitude graph shows that there is no direct relationship between the period and amplitude of a wave. The period and amplitude of a wave are independent of each other, meaning changes in one variable do not necessarily affect the other variable.
No correlation.

Any 2-dimensional graph - column/bar, line, scattergram will do the trick. It is difficult, though not impossible, to show such a relationship with a series of pie charts.
You can determine one variable from the other at any given point for that motion, and differentiating the graph gives you the speed at any selected point. You can do this without the plot itself but a graph shows the relationship clearly and immediately.
that there is a relationship between the two variables. This relationship can be used to predict how changes in one variable will affect the other variable.
