Gnuplot

Gnuplot creates plots in an outside application, which must be output into a png (or other image file format) in order to be read online.

After you install gnuplot and are running the application, You can create a data file which looks like below (lines which begin with a # are comments)
"my.data"

#this file is called my.data
1        1
2        2
3        3
4        4
5        5
6        6
7        7
8        8
9        9
10       10

You can then plot this data by writing the following

plot "my.data" using 1:2
set term png
set output "image.png"
replot
