1. A wireless controller for data visualization, comprising: a processing resource; and a memory resource storing machine readable instructions to cause the processing resource to: link data from sensors of physical objects to corresponding objects within a three-dimensional (3-D) visualization of an area; display the corresponding objects at a selected level of detail; alter a setting of the corresponding objects upon a selection of the corresponding objects; generate a simulation of the corresponding objects within the area based on the altered setting; receive data from the sensors coupled to the physical objects; and compare the data collected by the sensors to data from the simulation to determine degradation of the physical objects.
