There are several: PowerBi, Tableau, Looker.

Not sure if you can embed them in an app though.

There are also OSS alternatives like Superset, Jaspersoft etc.

But my main take is this:

try to avoid crunching large data interactively. I would try to prepare data as much as possible, then load that into some cache (f.e. powerBI import mode) and use that in your app.
