A system may include a display to present a visualization comprising a plurality of graphical indicators, each of the graphical indicators associated with a respective one of a plurality of entities of interest, a touch-sensitive input surface to receive a touch input at a first portion of the visualization representing a current physical location of the apparatus and a drag input on the display device from the first portion to a second portion of the visualization, and a processor to filter the plurality of graphical indicators based on a distance between the first portion and the second portion. Filtering of the plurality of graphical indicators may include determination of a second distance based on the distance between the first portion and the second portion, and determination of at least one of the plurality of entities of interest, each of the at least one of the plurality of entities of interest located less than the second distance from the current physical location of the apparatus. |
