How to Create Maps in Tableau

One of the strong features of Tableau is to create interactive Maps. Tableau automatically creates maps for the fields with geographical roles such as  Country, City, Zipcodes etc. Tableau automatically generates Longitudes and latitudes for such fields.

In this blog, i will create a Map using OHIO counties and Zipcodes. I have created a sample data set using Ohio County and Zipcodes.

My data set contains County, Zipcode and Sales for each zipcode. Structure of the data is as below
