Yes, it is already installed.  Execute "systemd-analyze plot > plot.svg.". 
This will but the chart plot.svg in your home directory.  To view it
double-click on the icon and a image viewer will display it.  In case the image
viewer fails (which happens to me on some plot files) you can use Firefox to
look at the plot.  You may not understand what is there so upload it where
anyone can look at it (I used Drop Box) and post the URL here,
