1. A computer-implemented method for graphically identifying candidate electrodes of a leadwire for stimulation of a patient anatomy, the method comprising: obtaining, by a computer processor, data corresponding to an anatomic region; identifying, by the processor, a spatial relationship between electrodes of the leadwire to the anatomic region; based on the identifying, selecting, by the processor, a subset of the electrodes of the leadwire; generating, by the processor and based on the obtained data and the selected subset, a graphical output arrangement that includes: a model of the leadwire including graphical representations of at least some of the electrodes; and a graphical selection marking identifying the selected subset of the electrodes; and displaying, by the processor, the graphical output arrangement on a display coupled to the processor.
