desired direction: in order to (IOT) be able to CRUD vega specs (clj/edn or js mode) I’d like to have HF version of vega live insta editor https://vega.github.io/editor/#/edited

here is my kind of working result http://alexandrkozyrev.hyperfiddle.com/:vega-editor/

replacement for (or addition to ) http://alexandrkozyrev.hyperfiddle.net/:dustingetz!vega-child/~entity('$',17592186046849)
