First time using Tableau Public. Dataset here: http://wwwn.cdc.gov/foodborneoutbreaks/ I downloaded the .xml file and then used Excel to convert it to a csv file for use by Tableau.
Ideas for interacting with the dashboard: Mouseover an outbreak circle on the map for details. Scroll through the months being displayed with the slider/arrows on the left. Alternatively, pick a bug type from to bottom and then check out the seasonality that exists in the bar charts at the top. Scroll the months with just a particular bug type highlighted. As always, mouseover for more details.
