It depends on how you want to implement it really. You could have a single Django app that has three different Dash apps hooked up to different Django routes, or you could have one single Dash app attached to a single Django route (as in my example) and use the Dash router.py logic to add different endpoints within the Dash app. I suspect the second option might be simpler. The first option involves either having three separate Flask instances (which seems a bit wasteful) or having them all try to reuse the one Flask instance, which adds extra complexity.
