It shows an animation of how the stats of the leading entries change over the course of the contest.
To answer the question of using data not normally on the MATLAB path, I offer the following modification.
warning ('This was an entry to the MATLAB programming contest (http://www.mathworks.com/contest/datavis/home.html). Please load the contest data and unzip it to place contest_data.mat on your MATLAB path.')
no H1 line, no help section, no example(s), loads a file, which the typical ML user does not have and, therefore, causes an error right away...
no appreciable benefit to any ML user...
This is a corrected version of the previous entry where I fixed the text describing the animation.
Included the .asv instead of the .m file. Corrected now.
