How to read it

1. A chord represents a dependency between data (ex: from "Europe" to "North America").

2. The chord base width is proportional to the value of the indicator based on the first dimension (ex : Departure from "Europe" = 41,290).

3. The chord color represents the balance of power between data, it take the color of the weakest (ex: Chord "Europe - Africa" use the color of "Africa").
