 - Visualizes tumor phylogeny and subclonal compositions as a Jellyfish plot.
 - Allows visualizing both temporal and spatial relationships between samples.
 - Sorts samples based on the subclonal composition and divergence, effectively grouping similar samples together.
-- Provides basic interactivity for exploring the plot, such as highlighting subclones and clusters upon hover or click, and displaying details in tooltips.
+- Provides basic interactivity for exploring the plot, such as highlighting subclones and clades upon hover or click, and displaying details in tooltips.
 - Generates phylogeny-aware color schemes for subclones, inspired by [Visualizing Clonal Evolution in Cancer](http://dx.doi.org/10.1016/j.molcel.2016.05.025) by Krzywinski.
 - Exports the plot as publication-ready SVG or PNG files.
