The visualization is an efficient way to find frequent patterns or relationships in a dataset. In this chapter, we were introduced to a number of basic graphs implemented with
D3.js. We discussed the most popular visualization techniques for discrete and continuous data. We explored the relation between variables and how variables work over time.
Finally, we presented how to integrate basic user interaction and simple animation, which will be used widely in the following chapters.
In the next chapter, we will introduce a variety of data analysis projects using machine learning algorithms as well as visualization tools.
