Take an easy example: you are displaying a Bubble chart that aggregates some data on some categories.
'Zooming in' (e.g. via mouse scrolling) would mean that going into detail for that category in focus would show all the data points behind that category.
Currently we would create a detail visualisation from the bubble chart to a scatterplot, but here we are zooming in to the same visual, it just changes 'Layers'
The same approach could be designed for bar charts, lines and similar.
We could have a kind of widget where the user can drag&drop a detail visualisation into to make it very general.
