I recently had a project for school where we created a data dashboard using the Tableau visualization software. My group chose to explore the growth of connectivity technology in the African continent over the last decade and a half. We specifically focused on the number and growth of mobile phone, internet, and landline users.
We were able to create some pretty beautiful visualizations that I think increases the usefulness of the data, so I thought I'd share it. The adoption of the communication technology over the last 2 decades has exploded across the continent, and there is a definite trend over the last 5 years to replace landlines with mobile. It's also interesting to explore the inward spread of the connectivity from the coastal cities to more inland, developing countries.
