HIERARCHICAL CLUSTERING

Create Dendrograms in 30 Seconds

Visualize hierarchical relationships and phylogenetic trees. Plotivy handles distance calculations, linkage methods, and tree rendering automatically.

Tree Visualization is Tricky

Distance Metrics

Calculating distance matrices (Euclidean, Manhattan, Cosine) and choosing linkage methods (Single, Complete, Average) is complex.

Branch Coloring

Coloring branches based on a specific cut threshold or number of clusters in Python/scipy requires tedious coding.

Label Alignment

Getting leaf labels to align perfectly, especially with large datasets, is a constant struggle in standard tools.

How Plotivy Creates Dendrograms

1

Upload Data

Upload your data matrix or distance matrix.

2

Describe Tree

"Create a dendrogram using Ward linkage. Color branches for 3 clusters."

3

Export

Download a high-resolution image or vector graphic.

Example Prompt

“Create a dendrogram for the uploaded dataset. Use Euclidean distance and Ward linkage method. Color the branches to show 4 distinct clusters. Orient the tree to the left and display leaf labels.”

✨ Plotivy AI uses scipy.cluster.hierarchy to generate accurate dendrograms.

Advanced Dendrogram Features

Flexible Layouts

Choose from top-down, left-to-right, right-to-left, or bottom-up orientations to fit your figure layout.

Smart Coloring

Automatically color branches based on a distance threshold or a specified number of clusters (k).

Truncation Options

For large datasets, condense the tree to show only the top levels or last p merged clusters.

Heatmap Integration

Easily combine your dendrogram with a heatmap to show the data values associated with the clustering.
