Visual Design Type: Bar chart
Name of Tool: Tableau
Country: All countries in the data set
Visual Mappings: Color (Primary_fuel), y-axis (capacity_mw, generation_gwh_2013,generation_gwh_2017), x-axis (primary_fuel)
Unique Observations: My observation is that from 2013 to 2017 the generation of renewable fuels has increased except in hydro. Also the capacity of geothermal and wind is less than their generation in 2017.
Data Preparation: I convert the file from .csv to .xlsx
1)Does my visual design make sense?
2)How can my visual design be improved?
