Data visualization

A picture is worth 1000 words.

A good graphic can often convey information about the data better than any other analysis. Some examples of the importance of using good graphics are provided in 10  Graphics.

In R, ggplot2 uses a standard syntax for creating myriad different types of plots, all based on the grammar of graphics, including the visual cues that convey information. 11  ggplot provides not only the technical syntax of ggplot2 but also it’s connection to visualization theory.

12  Shiny presents dynamic and interactive plots (using plotly and shiny), which provide even more ways for the user to engage with the information on the graphic.
