  The scary thing is that yea we can see these in 2D and maybe 3D. But ... usually there are more than 2 or 3 columns in our data :(

    It's clearly hard, but there are tools for doing exploratory visualization of high-dim data. GGobi http://ggobi.org/ http://ggobi.org/ and all the ones that arrange points but try to get local neighborhoods correct (t-sne, umap, et al.).

  Content warning: This is a baker’s dozen not a regular dozen, in case anyone clicks through expecting to find twelve and is mildly and briefly perturbed.
