\subsection*{Checkerboard plots}  We have also developed a second visualization, the checkerboard plot, to complement case tree plots. Checkerboard plots plots, seen in figure \label{fig:check}  show how cases in human to human clusters have occurred over time. They can be used in conjunction with case tree plots, or in situations where representing a hypothetical network structure is inappropriate. Checkerboard plots have the added benefit of showing each case's unique identifer, to more easily connect the visualization to the line listing. Like case tree plots, the x-axis of the checkerboard plot represents time. Each value along the y-axis is the indentifier of a human to human cluster. Each case in the cluster is represented as a colored square, and is labeled with the case's identification number. The plot can be generated using the same line listing as described for case tree plots.
