In this chapter, we will turn our attention to one of the oldest and well trusted companions in data visualization—charts. Charts are a well defined and well understood graphical representation of data; the following definition just confirms it:
(In charts) the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart.
Jensen C. & Anderson L. (1991)
When charts are used in data visualization, their well understood graphical semantics and syntax relieve the audience of your visualization from the burden of learning the meaning of the graphical metaphor. Hence they can focus on the data itself and the information generated through visualization. The goal of this chapter is not only to introduce some of the commonly used chart types but also demonstrate how the various topics and techniques we have learned so far can be combined and leveraged in producing sleek interactive charts using D3.
