Rick, Have you read about the Datasaurus Dozen (http://www.thefunctionalart.com/2016/08/download-datasaurus-never-trust-summary.html) created by Alberto Cairo? There have also been suggestions to rename this Anscombosaurus to honour Anscombe. The methods used to create the data sets are also computational, but use a tool to convert scatter plots to data while controlling the statistics. I'm working on a blog post to demonstrate these very dissimilar graphs at http://blog.hollandumerics.org.uk, but would welcome your statistical insight. ..............Phil
