2017: Chord diagram ICTS.team interaction

The 2014 version of the Chord Diagram created for the Global Mobile Consumer Survey held by Deloitte each year. It shows the flows of people between the phone brand of their previous phone and the current phone

For an explanation on how to understand this chart, please take a look at my "Storytelling" version of the same Chord Diagram but with 2013 data
