Generate a "cone of data" - 24 "hours" of 30-second samples that have increasing variance

conedata.js

/**
 * Generate a "cone of data" centered around a median value
 *
 * There will be 24 rows of data, each containing 120 samples.
 * Each row is centered around a "median" value of 50
 * Each row's sample is a random value multiplied by the "hour" so that
 *   later hours have a larger spread.
 *
 * This should have an obvious appearance in a plot
