I think there is some promise in the circos technique, but the author would be well served to eliminate some of his rhetoric. In particular, he should recall Tufte's advice that every visualization should serve to answer a question. Tables are very good for looking up information, in much the same way that a telephone book is good at providing the published phone number of a specific person or business. Despite reading through two examples, I am still unsure what relationships the visualization is particularly adept at highlighting. I don't know what "agnostic to the data domain" means, but I assume that it suggests that the visualization has application regardless of the questions being asked of the data. That attitude implies that the author fails to understand what makes visualization interesting and useful in the first place.
