Visualization and Graphical User Interfaces

GUI applications revolve around events, and F# provides a natural way to process events with functions. Graphical interfaces are often developed using visual editors, in particular to build GUIs by assembling controls. Applications, however, often need drawing capabilities for displaying and manipulating data, which requires custom programming to augment available controls. This chapter will discuss how to develop graphical applications with F# and why the functional traits of the language suit the event-driven programming paradigm typical of GUIs.
