Comparison of the accumulated number of food alerts and the transgressor indices.

<p>The Y axis corresponds to the accumulated number of food alerts made against a product from a given country and the transgressor indices (TI) for the top 25 transgressors. The line shows the number of food alerts made between 1 January 2003 and 1 July 2008 against the given countries. Bars represent the transgressor indices using PageRank and HITS, calculated with exponential weighting for 1 July 2008. Corresponding data are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0006680#pone-0006680-t001" target="_blank">Table 1</a>.
