Provide reactive notebooks in Quarto

[parmsam]

Description

Consider adding reactive notebook similar to reactor in R, ipyflow in Python, or Pluto.jl in Julia. Could be a special mode similar to the visual editor for Quarto. Would make relevant chunks update based on data changes in the notebook, making experimentation easier without the need to re-excute previous lines of code.

From what I understand reactor requires an R session since they can be run via shiny, it is already supported, see https://quarto.org/docs/interactive/shiny/.

ipyflow is a Jupyter kernel, thus already supported, see https://quarto.org/docs/computations/python.html#kernel-selection.

Pluto.jl is not compatible with Jupyter, it is an alternative, so unlikely Julia supports will be in two different system.
