In this tutorial, I'll guide you through Dash and its callbacks, in order to add interactivity to our dashboard. Since it involves using the decorators, it can be challenging to get it right when you start. I'll give you some tips that might save you a lot of time in the process!
Towards the end, I'll add another output and demonstrate how you can use one single user input to feed multiple dashboard elements.
