 Plotting
 --------
 
-The goals of this "project" include a) familiarizing myself with a few sorting
-algorithms by examining their (possibly, simplified) implementations and b)
-studying the way algorithm's running time changes in relation to the length of
-its input (a.k.a. identifying its time complexity).
-
-A simple way to visualize the way algorithm's running time changes is to make
-appropriate measurements and plot them on a nice graph.
-The results of course are highly dependent on the hardware used, while the
-graph's look depends on the software used for rendering.
-
-I've made the measurements for each of the implemented algorithms and put the
-plots to the "plots/" directory.
-Both the hardware & the software that were used to produce the plots are listed
-below.
