The Documentation for AspectRatio on its first line under the "Details" section states: "AspectRatio determines the scaling for the final image shape" (emphasis is mine). But the practice shows that is it not true: it seems that this option affects only aspect ratio of the plot range but not the aspect ratio of the whole image (with ImagePadding and ImageMargings added). It is a basic graphics option but we still know a little about it...

What the option AspectRatio actually do? How it interacts with PlotRangePadding, ImagePadding, ImageMargings and ImageSize?

It would be ideal to have a mathematical model of interaction between these options.
