$0 [ -g | --graphical ] afl_state_dir graph_output_dir
This program generates gnuplot images from afl-fuzz output data.
Usage:
afl_state_dir should point to an existing state directory for any
active or stopped instance of afl-fuzz
graph_output_dir should point to an empty directory where this
tool can write the resulting plots to
-g, --graphical (optional) display the plots in a graphical window
(you should have built afl-plot-ui to use this option)
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.
