1 Project Topic

The subject of this present project is to make visualizations from data about food consumption habits of the French population. Data are from a survey of ANSES, an agency of the French government. Its purpose is to acquire data about changes in consumption habits and patterns, new issues in the areas of food safety and nutrition in France. This proposal is based on the third round of the survey which took place in 2014-2015. I plan to make some visualizations from this round only. Indeed not looking at changes in between rounds.
