Generates `numpy/fft_plot.svg`, the plot of $2 \sin(t) + \cos(4t)$ with 25 points and its <DFT>.
The output was also uploaded to: https://commons.wikimedia.org/wiki/File:DFT_2sin(t)_%2B_sin(4t).svg and added to https://en.wikipedia.org/w/index.php?title=Discrete_Fourier_transform&oldid=1176616763 only to be later removed of course: <Deletionism on Wikipedia>.
