Plotting word frequency histogram using gnuplot

问题

I'm using gnuplot to plot the histogram of the following data file.

data.txt
=========
countries       1
domestic        1
fourth-largest  3
in      4
airline 5
and     8
destinations    3

I want to plot the histogram of word frequency(y axis) against the word(x axis).
