1. A method performed by a system, the method comprising:
receiving, by a communication interface of the system, sensor data indicating a position of at least a portion of an instrument;
determining, by control circuitry of the system, an orientation of the instrument based at least in part on the sensor data;
determining, by the control circuitry, a target location within an anatomy;
determining, by the control circuitry, a plane that includes the target location;
determining, by the control circuitry, a projected position of the instrument on the plane based at least in part on the orientation of the instrument;
determining, by the control circuitry, a planar distance between the projected position and the target location on the plane; and
generating, by the control circuitry, one or more interface elements for display, the one or more interface elements indicative of the planar distance between the projected position and the target location on the plane.
