 ### 2D Mechanisms
 
-To visualize mechanism data logged using a [`Mechanism2d``](https://docs.wpilib.org/en/stable/docs/software/dashboards/glass/mech2d-widget.html), add the mechanism field to an existing robot or ghost object. The mechanism is projected onto the XZ plane of the robot using simple boxes (as shown below). The robot's origin is centered on the bottom edge of the mechanism.
