Abstract : Each domain has its graphical archetypes. In particular, spheres are unavoidable components of domains such as geography or astronomy. However, when perusing a number of publications, we noticed that spheres were often incorrectly drawn with respect to their features such as great circles and parallels. This article examines several simple METAPOST techniques that remedy these problems.
