Function chaining
As we have seen so far, the D3 API is completely designed around the idea of function chaining. Therefore, it forms a DSL for building HTML/SVG elements dynamically. In this code example, we will take a look at how the entire body structure of the previous example can be constructed using D3 alone.
Note
If DSL is a new concept for you, I highly recommend checking out this excellent explanation on DSL by Martin Fowler in the form of an excerpt from his book Domain-Specific Languages. The excerpt can be found at http://www.informit.com/articles/article.aspx?p=1592379 .
