A visualization of people who have witnessed historical events

This application shows a simple visualization of people who witnessed select historical events (from 1991). We plot the number of people who originally witnessed the event alive vs years. Each graph shows a decreasing trend which signifies that the number of people who originally witnessed the event are declining over the years.

The pie chart shows the number of people (who witnessed the event) living in 2014 vs the people who did not witness the event (population born after the event).

A video demo of the application is available here.
