Using maps for data visualization in Tableau

Tableau has powerful built-in tools to visualize data on maps. In fact, this map based visualizations would give more insight about geolocation information bounded to the dataset. In order to load location of plants, you need to put Longitude in Columns and Latitude in Rows and make sure you disabled Aggregate Measures:

Now put Industry groups into the Marks and change it Color and put the Facility Name as well into the Marks:

Now put the reported CO2e emissions into the Marks and change it to size:

As a result, we incorporated the CO2 emissions into the location plants by using map visualization.

In order to visualize a specific region in the US map, you need to create a new group called Region and put these states into different groups:

  • South East: AK, AL, AR, FL, GA, KY, LA, MS, NC, SC, TN, VA, WV

  • North East: CT, DC, DE, MA, MD, ME, NH, NJ, NY, PA, RI, VT

  • South West: AZ, NM, OK, TX

  • West: CA, CO, ID, MT, NV, OR, UT, WA, WY

  • Midwest: IA, IL, IN, KS, MI, MN, MO, ND, NE, OH, SD, WI

Now put, Region into the Filter and choose South East and Industry groups into the Filter and choose Power Plants and Petroleum and finally put Industry groups on Color (in Marks) and reported CO2e emissions into the Size (in Marks):

If you change the Marks from Automatic to Density, you will find this heat map:

Finally, put the State on Columns that would lead to automatic generation of longitude and latitude of states and put the reported CO2e emissions into the Marks and change it Color and use Region in Filter to choose South East:
