Write a bash script that plots the round$-$trip times $($RTTs$)$ from a CSV file according to the format$$from the previous shell script, using gnuplot. The script should accept one argument: the name$$of the CSV file. The script should plot the RTTs as bar chart. The x$-$axis should be the domain, and$$the y$-$axis should be the RTT in milliseconds. The script should also include a title and labels for$$the x$-$axis and y$-$axis.
