The current matplotlib architecture

The current matplotlib architecture revolves around the operations that are necessary for the users to create, render, and update the Figure objects. Figures can be displayed and interacted with via common user interface events such as the keyboard and mouse inputs. This layer of interaction with common user interface is called the backend layer. A Figure needs to be composed of multiple objects that should be individually modifiable, but it should be implemented in such a way that it has a positive and predictable impact on the other aspects of the Figure. This logical layer is responsible for the abstraction of each visual component that one sees in a Figure. Due to its highly visual nature, this layer was identified as the more general concept of creating visual art and is thus referred to as the artist layer.
