Labeling is a key feature in creating insightful plots and charts by allowing elements to have additional information such as names or values closely associated with them. Version 12 extends the classes of objects that can be labeled to include points, curves, parametric regions and surfaces in both 2D and 3D. Simultaneously, there are significant performance improvements in both faster labeling and better automatic positioning of labels. In addition to the automated labeling algorithms, the system still provides easy yet full control of how to place and style labels and callouts when needed.
