In this chapter, we looked at data visualization in F# and learned to build user interfaces. We have looked at how to use F# to create user interfaces without a visual designer. There are pros and cons of using this approach of course. The main benefit is total control and there is no hidden magic. On the other side, it can be time consuming when we talk about larger GUI applications.
In the next chapter, we'll use the data visualization tools introduced in this chapter to study some interesting properties of options. We'll talk about the basics of the options and how they are priced using the Black Scholes formula. Also, the Black Scholes formula will be implemented in F# and discussed in detail.
