[adrienpacifico]

Location of the documentation

Ecosystem (wepage), ecosystem.rst (file)

Documentation problem

• There is some deprecated library:
  qgrid is one of them.

• There is some cutting edge/popular library that are missing
  Great expectation is probably one of them.

Suggested fix for documentation

Deprecated library

• List deprecated libraries
• Remove deprecated libraries (or put them in a deprecated section)
• Replace deprecated package for the best (or bests) available alternative
• [Governance] Define criteria for "what is a deprecated package" or a governance system (e.g. is @TomAugspurger Engarde library deprecated?)

library to include

• List potential library to include

  
  Great expectation ,
  Pandas-profiling,
  ipydatagrid,
  VS-Code,
  missingno
  streamlit,
  dataprep,
  mito,
  ⚠️This list is clearly no exhaustive.⚠️

• Define which to include or not
• [Governance] Define how to define packages to include

I am willing to try to do the job if I am helped ;-)

Ps:
This issue is related to #24927

Consider adding itables, ipyaggrid, and cuDF. qgrid has been forked by QgridNext.
