The DOT diagram views are redesigned for content and legibility, identically in both packages.
Every view opens with a shared Meridian style prelude: Helvetica type and role-coloured rounded nodes (teal constructs, amber propositions, navy predictions, green and red outcomes, paper scopes, grey rivals, a navy theory hub). Labels are word-wrapped so nodes stay narrow; workflow and pipeline nodes carry the id together with the relation or type rather than a bare word; the development roadmap chains its items into a single column instead of an ever-wider row; and the theme landscape colours themes by status. Every view now fits a documentation column without horizontal scrolling.
The intermediate representation remains byte-identical across R and Python; the goldens, tests and specification (API_SPEC.md section on diagram formats) track the new format. Both twins move to 0.4.0.
