A multi-panel plot for visualizing seasonal signatures of salmonellosis monthly rates in the US from 1996–2017. This includes overlaid annual time series plots of monthly rates, a box plot of average monthly rates for the 22-year period, and overlaid annual radar plots of monthly rates. Background colours indicate the four seasons defined by solar solstices and equinoxes: winter (blue), spring (green), summer (yellow), and autumn (orange).
