I am a Swansea Uni Student doing a Data Visualisation coursework and I would like somebodies opinion on these two geographical maps. Are either of these good examples visualisations of the infection count per state? Which one represents the data the best? Any constructive criticism is welcome!
Visual Design: 3D Mapping
Name of Tool: Excel
Year: 1951 -2007
Disease: Hepatitis B
Visual Mappings: The states are coloured in purple, the darker the shade the higher the number of recorded infections. The bar charts are coloured yellow in order, they offer an alternative way of mapping the level of infection per state and allow for better comparison between them.
Observation: The highest levels of infection occur in the states with the largest population, therefore there is a direct correlation between population size and infection rates.
