abstract = "Food data comprise records regarding nutrients, ingredients,
amounts of different vitamins and minerals that can be found in
foods. The wide variety of food products that can be stored in
large datasets makes the traditional analysis tasks unfeasible and
time-consuming when conducted manually by the dietitians and
related professionals. This paper describes a method for
visualizing food data using point placement strategies to support
specialists in tasks related to determining similar food products
that can be replaced in specific diets. The proposed method
generates a structured representation for food data to be used as
input to some state-of-the-art and recent visualizations, such as
PCA, t-SNE, UMAP and TriMap. Experiments were conducted to assess
the quality of visualizations and the results reported that the
nonlinear visualizations presented satisfactory discriminability
regarding some food categories and better preservation of the data
patterns. A case study based on a visual exploration process was
also conducted and demonstrates the specialist successfully
finding substitute food products for planning a vegan diet plan.",
