Dual Axis Map and Dual Encoded Circle Maps of Global Internet Usage

Dual Axis Map of Global Internet Usage (Lab 5 Part 1)

This is a dual axis map of global internet usage that we used the Tableau saved data sources under world indicators to create. This map is a cloropleth map that shows average internet usage per capita across the world. This map also has a cirlce across each region that shows the number of internet users with a circle with scaling size to represent the value. This map is effective because it helps to solve some of the geographic biases that happen due to the size of certain countries. As we discussed in last week's discussion, there are biases where people often believe that smaller sized values are less important, or in this case, small countries. This helps solve problems such as the fact that countries such as Russia or Canada which are huge, might have actually small numbers of internet users. Additionally, layering on the circles on top of the shaded regions helps the map viewer to recognize the relationship between a country's development and its global internet usage footprint.

Dual Encoded Circle Map of Global Internet Usage (Lab 5 Part 2)

This is a dual encoded circle map that we used the same Tableau data source as the map above. This map has circles that represent the internet usage per country/region with appropriate size and color. This map is effective because it has two different variables represented in the same peice of data. This helps the users scan and catch the contrasting circles with their dark borders. However, I feel like this map is not as effective as the Dual Axis map of global internet usage above because it combines the data together too broadly. Personally, I feel it is more effective to have the data separated as in the map above. Ryan Facks - zID 2027325
