@hebertodelrio - I hope you don’t mind that I gave it a shot. Just wanted to show you how easy it is to use Vizro which is built on top of Dash for this. I’ve added less than 20 lines of code to your existing code and managed to create the app within 15 min, thanks to all the heavy groundwork you did on the chart! 
I left most of your code unchanged so you can recognise it
