Appendix

Types of Graphs

The first type of graph that we will present is the line graph or line chart. A line graph displays data as a series of interconnected points on two axes (x and y), usually Cartesian, ordered commonly by the x-axis. Line charts are useful for demonstrating trends in data, such as in time series, for example.

A graph related to the line graph is the scatter plot. A scatter plot represents the data as points in Cartesian coordinates. Usually, two variables are demonstrated in this graph, although more information can be conveyed if the data is color-coded or size-coded by category, for example. Scatter plots are useful for showing the relationship and possible correlation between variables.

Histograms are useful for representing the distribution of data. Unlike the two previous examples, histograms show only one variable, usually on the x-axis, while the y-axis shows the frequency of occurrence of the data. The process of creating a histogram is a bit more involved than the line...
