While there are a number of review papers on trajectory visualization techniques, this paper provides a systematic taxonomy of current visualization methods through the lens of cartography and with a special focus on the `human user' (e.g. data scientist, analyst, domain expert, etc.). We systematically classify different techniques based on their visual specifications and functional elements according to the Cartography Cube model. The proposed taxonomy highlights the functionalities of different visualizations for mapping various aspects of multifaceted movement data. Trends and gaps in the literature on movement visualization over the past ten years are discussed. Our review suggests that future research should focus more on the role of the `human' in the development of human-centered visual analytic and exploratory tools, while providing functionalities for mapping uncertainty and protecting individual privacy in knowledge discovery of movement. These tools should be guided by a Cartographic framework and visual principles specifically pertinent to movement.
