How can I plot the variability of a large data set?

I have a data set of wind speed which consists 15789 data point(data duplication may exist). I have to plot the variability of these data set.

Please define ‘variability’. Do you mean maximum and minimum, the statistical measure of variance (or standard deviation), or something else?

Actually, I want to plot the spread(variability) of the data points.
