An example how to make a quiz with you-draw-it with displaying reference values.
For documentation see https://github.com/EE2dev/you-draw-it
Adopted the you-draw-it implementation from the great work at https://github.com/wdr-data/you-draw-it. Original idea developed by the New York Times.
forked from EE2dev‘s block: you-draw-it reference values (with style)
