I have a text file that represents the runtime of a specific script, with each line representing one run:
141
124
156
204
498
512
444
374
189
120
143
132
One can see that the section that I pointed out represents a spike in the script runtime. Is there any package which will make an ascii-art graph out of this data, which could be viewed with cat or vim? I could write a script which, when given a terminal width, split the file into lineCount / terminalWidth chunks, average them, and then by column make a graph of the data. However, if there already exists such a package then I'd love to know about it.
Thanks.

Stackoverflow has a very similar question. As I cannot mark this Superuser question as a dupe of the Stackoverflow question, I'll summarise here: The application that can make an ascii-art graph out of the data is gnuplot.
gnuplot> set terminal dumb
gnuplot> plot "runtime.txt"
