## What it is
pyCirclize is a Python package built on matplotlib for creating circular visualizations such as Circos plots, chord diagrams, and radar charts. It also provides specialized genome and phylogenetic tree visualization methods for bioinformatics workflows.

## Use cases
- draw a circos plot in python
- create a chord diagram from a matrix
- visualize comparative genomics between genomes
- plot a phylogenetic tree in python
- make a radar chart with matplotlib
- visualize microbial genome features circularly

## When to choose
- you need publication-quality circular plots in Python with a matplotlib-based API
- you work in genomics and need Circos-style genome or phylogenetic tree figures
- you want a pip/conda-installable alternative to R's circlize

## When to avoid
- you need general-purpose non-circular plotting (use matplotlib or seaborn)
- you prefer an R environment where the original circlize package exists
- you need interactive web-based visualization rather than static figures

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts
- domain: data-visualization, bioinformatics
- platform: python, cross-platform
- tags: circos-plot, chord-diagram, radar-chart, matplotlib, phylogenetic-trees, comparative-genomics
