      A hypothesis: for live programming to scale beyond toy programs, generic low-level visualizations aren't enough. Instead, we need Live Literate Programming: better tools for creating *program-specific* views, which communicate our higher-level understanding.

      Bearish on program visualization right now. People have been trying to vis code for half a century, and nothing has worked. All we have are Doxygen inheritance diagrams. My guess: without a more principled understanding of program comprehension, we can't build effective vis.

      i'm curious, does that include "visualizing the code" and "visualizing the data"? i'm bearish about the former, but believe in the latter

      Geoffrey Litt Retweeted Glen "Electrify everything now" Chiacchieri

      Also curious what you think of Glen's examples in the thread To me, these make it crystal clear that interactive explanations can be really helpful in certain cases -- the question is whether it can be made easier to produce thesehttps://twitter.com/Glench/status/1253739930360123401 …

      This is another example: http://glench.com/MarilynMaloney/  That demo showed me that with a change of representation even kids could understand a program that would have been basically impenetrable unless a helpful adult was there to explain things.

      I think those are great! There are many good bespoke program visualizations, Learnable Programming being a classic example. I'm more questioning the viability of *generic* program visualization. I recommend this paper: Steve Reiss, “The Paradox of Software Visualization.” 2005

      And the situation has not demonstrably improved since, at least within the software vis community. See: Merino et al. "Towards Actionable Visualisation in Software Development." 2016pic.twitter.com/x5dwE4ypo1

          Thanks for the refs. I’ve thought about repurposing Sketch-n-Sketch for program vis. I don’t have time for it but if someone wants to explore that, feel free to get in touch!
