Introduction

Sankey diagram for Greenland and Antarctica.

Uses scripts and CSVs to automate generation to support graphics for different years, models, etc.

Methods

• Any number of CSV files containing the variables (and other values) shown above can be placed in the dat folder. See ./dat/README.org for details
• Running make will then generate a Sankey diagram for each CSV file by injecting the variables into a template
