The recently released Google Inbox app is a re-thinking of the email inbox experience that beautifully demonstrates Google's material design interactive animation language. This prototype focuses on the compose button's animation. Click the + to reveal a new state where a wave of buttons and labels float up, and the + becomes a pencil icon. It uses two states, with staggered animations.

I simulated a 10 second timer that counts down from 10 to 0. This is very simple to do. All you need to do is change the text property of the text value with a custom value and include a delay of 1 second. Then add a callback for the next number with a delay of 1 second. Repeat this until you get to the number 0. There is no need to use variables to simulate a timer.

Use a slider component to see the how a map of the US changes every month over a year based on the concentration of a fanbase. Uses a basic variable to change the container state of the map, with map assets created in Sketch. See how a version of it was created step-by-step within the Dashboard & Data Visualization webinar: http://docs.proto.io/videos/using-proto-io-for-dashboards-and-data-visualizations/ tags: variable | variables | data visualization | data viz | map | slider | states | months | USA

A data visualization where a bar chart of faces flies out showing the details of individual faces.

If you need to get the Y position of a vertically scrolling container, create a text box. Then on the container scroll trigger, set a variable that evaluates the numerical callback value from the event (Y position). Then add a callback that changes the text property of the text box by reading from the variable.
