What are Parallel Sets?

Parallel Sets is a visual analytics technique for exploring relationships within multidimensional categorical data. Unlike parallel coordinates, which focus on continuous variables, Parallel Sets uses width-proportional ribbons to show how categories intersect and flow between dimensions. This makes it ideal for uncovering patterns, distributions, and bottlenecks across taxonomies, survey responses, demographic data, segmentation models, or any dataset defined by discrete attributes. The result is a clear, interactive view of how categories combine—showing both structure and proportion in a single unified visualization.Developed as part of the broader Cass D3 Visualisations family, this plugin supports live preview inside the editor, dark-mode awareness, reusable data configuration, and flexible customization. It is ideal for visualising WordPress taxonomy data or any JSON-based categorical dataset.
