  We presented a novel geometric interpretation of the Riemann-Liouville
fractional integral. We found that a Riemann-Liouville integral can be thought
of as the area obtained by summing together the area of an infinite number of
non-rectangular infinitesimals whose shape is determined by the order of
integration {\alpha} and the integration limit t. We also showed that this
geometric interpretation offers many pedagogical benefits as it is very similar
in nature to the geometric interpretation of the Riemann integral.
