prefviz: Visualizes Preference Data via Ternary Plots in Two and Higher Dimensions

Visualises preference and ranking data by extending traditional ternary plots to support high-dimensional simplexes. The package provides methods to transform compositional data into coordinates suitable for 2D and high-dimensional ternary plots (see Cook & Laa (2024) <https://dicook.github.io/mulgar_book/>). Compatibility with interactive visualization packages such as 'plotly' or 'detourr' allows users to explore high-dimensional preference structures dynamically.
