All, Thanks millions for your comments. Devon (especially), your comment about my first link is very fair. The second and third links are more interactive than the first one, but I could not find a working example of them and therefore could not readily refer you to such, but it reacts in both directions: from histogram to pie chart and differently from pie chart to histogram. A link at the bottom of the blog at datsmith.org you mentioned was most insightful to me http://www.datasmith.org/2020/02/28/automatically-inferring-relational-structure-from-files/ . The author is explaining an approach he used in Datasmith (about which I know nothing). And his description gives vocabulary and ideas which were very innovative to me. (As an aside, another one of his blogs at the bottom of your linked page, was about the game rock-paper-scissors. What fun?)
I was able to find a link to Datadesk in the meanwhile. It is really a stunning application, for visual interactive analysis. You can get a great, quick intro at this link https://datadescription.com/data-desk/ if you viewin the video clip entitled, "DDRP Quickstart." Just seeing that video reminded me of how inspiring Velleman's application was to me. I wish I needed Datadesk. I think of J as being a great way to develop exploratory analytic models and somehow Datadesk tickles similar impulses for me; I have wondered if there would be a direct way to expand J in the direction of Datadesk. Raul (especially), your covid link is very typical. It reminds me of some of the newer interactive links I have noticed at nytimes.com. The latter can be quite informative but often require some explanation because of their novelty. On Sun, Nov 8, 2020 at 9:58 AM R.E.
