When strikes happen, from where do they originate?
Our data set contains a dimension marked with a globe called Origin State. The globe indicates that Tableau
has automatically identified the field as containing geospacial information. Select that dimension, then open
the "Show Me" menu in the upper right of Tableau. Tableau will give you the option of creating different types
of visualizations based on the types of dimensions and measures selected. Tell Tableau to create you a map.
Maps are good for visualizing location data, but can be overused. Maps are very good for seeing general
spatial distributions, and for complementing other visualizations that give more specific information. (A map,
for example, is very good as a filter on a dynamic dashboard.)
Hint: Once you have a map, try dragging measures onto the map to see how the visualization automatically
adjusts.
TODO: In the next tab title "Geographic Indications", recreate the visualization above.
Source data:
1) Select (left click) "Origin State" on the dimensions shelf.
2) Drop down the "Show Me" menu in the upper right corner and click the filled map
icon.
3) Drag "Number of Records" from measures onto the visualization. Tableau will make an educated guess and assign "Number of Records" to color. We could do the same thing by dragging "Number of Records" directly to the color box on the marks card.
4) Change the color palette by clicking the upper right of the color caption and going to "edit colors." Choose the red-green color palette and check "reversed" to make red represent the high end of the spectrum.
