I'm trying to create a project with Pi, my part of the project is create the GUI of it, basically I should find a way to display gauges (different shapes, circular, vertical...etc) for different reading of sensors connected to Pi. Also I should provide buttons and sliders to control some functionalities. All of this should be displayed by the touchscreen, what would be the best way to go with it? should i use Kivy or Tkinter? or maybe another library you recommend?
