Visualisation

The OFF database contains a huge amount of data. So much data that its relevance and meaning is hard to grasp, whether we are talking about individual products or sets of products. This is where visualisation comes to the rescue. With a simple image or plot the complex data is summarised and the conclusions can easily be drawn. On this page an overview is given of visualisation types that have been used for OFF data with examples and tools that can be used.

Types

• Labels which summarise data in a simple image (Nutriscore, NOVA, Ecoscore);
• Bar charts to present the total counts for a set of categories;
• Bubble charts
• Scatter plots to present the dependency between two nutrients for a set of products;
• Pie charts to present fractions for a set of products:
• Box plots to present statistics of a nutrient for a set of products;
• Violin plots to present the smooothed distribution of a nutrient for a set of products
• Line charts
• Radar charts
