This was a visualization of a JSON dataset without any numbers or text.
I chose to visualize the infection rate of HIV worldwide from 1990 to 2016.
EXPERIMENTING WITH CODE
If the User moves the mouse on the screen from left to right, they see all the HIV infections worldwide.
Left is 1990, right is 2016.
If the User clicks on one of the countries he comes to the second level which shows all of the infections from 1990 to 2016 in this specific country individually.
By clicking two more times the User can see the new infections in that country and also the death rates shown in blue. By clicking yet again the User will come back to the beginning.
