Choropleth Map Legend Design for Visualizing the Most Influential Areas on the Topic of Anesthesiology: Bibliometric Analyses

Abstract

Anesthesiology is the medical specialty of anesthesia or anesthetics [1] and the practice of medicine that is dedicated to the relief of pain and total care of the surgical patient before, during and after surgery [2]. Anesthesia is defined by the American Society of Anesthesiologists, anesthesiology as the loss of sensation with or without the loss of consciousness [3]. Many articles have illustrated the use of choropleth map (CM) in health outcomes across areas, such as dengue outbreaks [4, 5], disease hotspots [6], and the Global Health Observatory (GHO) maps on major health topics [7], have been presented in the literature.
