I used part of the "Laundry App UI Kit Sketch Resource" design that was designed by Satheesh Kumar at: https://www.sketchappsources.com/free-source/3397-laundry-app-ui-kit-sketch-freebie-resource.html to create a quick prototype

This prototype showcases a new Proto.io feature called Gradients, it’s a new way to create and animate gradients straight in Proto.io. You can now make your UI pop with vibrant linear or radial colors, and bring to life with beautiful animations.

This is a simple way to create an interactive line graph. There is another way to create it which involves Draggable Elements instead but that requires a much more complex setup. Go ahead and import the project in your account! By seeing the interactions you will realise how easy it is to recreate. p.s not the smoothest animation but feel free to improve it
