A series of small images illustrating distribution patterns of food products sold by a German food retail company stratified by zip codes.

<p>For illustration purposes, all product clusters containing exactly three products are displayed. Clusters are arranged in two columns of seven clusters each. Other cluster sizes exhibit similar correlations between product distribution patterns. This image is published with permission from Esri and its data providers, and from Michael Bauer Research GmbH, Nürnberg, Germany; Data Source: Microm 2013.</p

Number of case reports per location for several different outbreaks each generated based on a different product.

<p>For each product the results are averaged over 50 trials. For each trial, the x axis is sorted from most to least frequently occurring location to show the outbreak pattern.</p

Hierarchical clustering diagram of 580 food products.

<p>Different colors indicate different clusters, defined by a cut-off value of 0.25. (Note that colors were used multiple times, i.e., non-adjacent clusters of the same color are not related in any special way.)</p
