I was wondering if anyone has any more information on why ggvis was archived.
The website says that it was archived because its not seen as the most pressing problem. But this seems a little weird. Lots of problems are not the most pressing, but they are still worth doing the bare minimum and not archiving.
I think they have limited bandwidth for projects they can work on at any given time and since plotly already provides a mature solution for the same needs ggvis was shooting for, they felt it was no longer relevant enough to commit resources to it.
