I’m studying at Swansea University Computer Science and I’ve been asked to produce some visualisations for global Power Plants. Please find below one of my visualisations and do feel free to add any comment.
Visual Design Type: Packed Bubbles
Name of Tool: Tableau
Year: All years of the dataset
: * colour: colour mapped the Primary source of energy in China.
: * shape: each circle represents a type of Fuel
: * size: the size of each circle is based in the Capacity Produced from the specific Fuel
: From the visualization, we can see China’s Primary Fuels
i.e. we can see that China is producing the most its energy
from Coal, Hydro and Gas.
: Transforming the CSV file to the XLSX file
Do you understand what the visualisation shows?
Is there any other visualisation map type more suitable for this case?
Is the colour map optimal?
Should I add any additional label?
