define the data separator if it's not a space.
enclose the filename in quotes because it's a string.
use 'splot' for 3d plots.

set datafile separator ","
splot "data.csv" with lines

Hi igalis,
please be aware that "," is a bad separator since other countries
use it where the english use a ".", more over it does not improve
readability of the files.

just my two cents, i stumbled over that problem some time ago

After I enter the splot command into the linux terminal, nothing happens. I'd
expect a new window to open with the plot? Is this related to the
configuration of Linux (ubuntu, on my pc), or do i need to enter a different
command for the plot to actually appear?

when starting gnuplot, some information is printed.
the last line tells which terminal is used.
what's written there? 'unkonwn'?
