I think there's an issue with the histogram rendering in this post. The rapid descent from the spike on the left is not consistent with high ECDF impact and the apparent binning resolution visible in the piecewise line-segments. In general histograms should not be visualized with connected line-graphs in this way - the standard bar graph depiction makes the bin-width apparent and resolves some of the issues the article needs the ECDF for (e.g. relative impact can be assessed visually by comparing the relative areas of the associated bars). The bar visualization also makes it possible to use varying bin sizes, which is extremely useful with any distribution that has tails.
