Add visual representation of the sensor data in Studio

Created by: stephanemagnenat

This is a wish from Wm Brown:

I think it would help the visual (and text) programming language if there were some sort of chart/diagram of the thymio with all of the sensor feedback shown, along with the current values and min/max values- say a static picture, or a 3D diagram with all of the indicator LEDs and their response levels indicated. It’d allow kids to see how the Thymio sees the environment right on the screen, without having to look around at the robot or match up the sensors and displayed data.
