Hot spots are locations where mantle plumes rise up and melt, causing magma to rise to the surface independent of plate boundaries. This leads to the formation of volcanic features such as islands or seamounts. Subduction zones and mid-ocean ridges are both associated with plate boundaries, and transform faults are areas where two plates slide past each other horizontally, so they are also not independent of plate boundaries.
