Principle to Show Cluster Membership | Visualization Component | Clustering Algorithm | |||
---|---|---|---|---|---|
Main | Secondary | Â | Hierarchical | Partitional | Density-based |
Similarity (color or size) | Proximity | Scatterplot + Color | Δ | Δ [17] | Δ [16] |
 |  | *Graph (vertex as item) + Color | Δ | Δ [5] | Δ [16] |
 |  | *Bar chart (Reachability Plot) | X | X | |
 | Enclosure | Colored shape | Δ [25] | Δ | Δ [13] |
 | . | *Parallel coordinate plot + Color | Δ [6] | Δ | Δ |
Proximity | Similarity and Enclosure | Bar chart (Silhouettes Plot) | Δ | O | |
Connectedness (line connection) | Similarity and Proximity | *Dendrogram | X | Δ | |
 |  | Normal tree | Δ [26] | X | Δ |
 |  | Circular tree | Δ [26] | X | Δ |
Enclosure | Proximity | *Heatmap + Partitioning | O | O | O |
 | Similarity and Proximity | Treemap | Δ [26] | X | X |
