This program generates gnuplot images from afl-fuzz output data. Usage:

$0 total_state_dir graph_output_dir graph_title

The afl_state_dir parameter should point to an existing state directory for any
active or stopped instance of afl-fuzz; while graph_output_dir should point to
an empty directory where this tool can write the resulting plots to.

The program will put index.html and three PNG images in the output directory;
you should be able to view it with any web browser of your choice.
