Where is the variable always located on a graph?

On a graph, the variable is typically represented by the axes, with the independent variable plotted along the x-axis (horizontal) and the dependent variable plotted along the y-axis (vertical). This arrangement allows for a clear visualization of how changes in the independent variable affect the dependent variable. In some cases, particularly in more complex graphs, additional variables may be represented through different dimensions or by using color or size to convey additional information.
