Map and bar visualization

Visual Design Type: The mean capacity of different type pf different continent

Name of Tool: Tableau

Country: All of the countries in the dataset

Year: All of the years in the dataset

Visual Mappings: This visualization consists of a topographic map and six pie charts. In the topographic map, according to the six previously divided continental plates, each plate depends on the form of energy power generation. Different colors represent different types of energy. The size of the circle indicates different capacity. The larger the circle, the more capacity. Six pie charts represent different types of energy on different continental plates.

Unique Observation: As can be seen from the first figure, most of the continental plates rely on nuclear power and coal for power generation. It can be seen from the six pie charts that Africa mainly relies on nuclear power generation, Oceania mainly relies on coal for power generation, Europe mainly relies on natural gas for power generation, Oceania mainly relies on oil for power generation, South America mainly relies on geothermal energy for power generation, and North America mainly relies on natural gas for power generation.

Data Preparation: Different countries are classified according to their different continental plates. Then visualize their corresponding data.
question:
• Does my visual design make sense?
• Is my choice of color map optimal?
• How can my visual design be improved?

I think this design is very good. The information on the map is related to the information on the pie chart. I can see clearly on the pie chart the type and proportion of energy generation used in each state.
