## What it is
plotnine is a Python data visualization library implementing the grammar of graphics, based on R's ggplot2. Plots are composed declaratively by mapping dataframe columns to visual properties, with layers, facets, scales, and themes.

## Use cases
- create scatter plots and statistical graphics in python
- ggplot2-style plotting in python
- build publication-ready figures from pandas dataframes
- facet plots across multiple panels without loops
- incrementally compose complex visualizations
- exploratory data analysis plotting

## When to choose
- you know ggplot2 and want the same grammar in Python
- you want declarative, layered plots built from pandas dataframes
- you need faceting, automatic legends, and sensible defaults for statistical graphics

## When to avoid
- you need interactive or web-based dashboards rather than static figures
- you prefer matplotlib's imperative API or need pixel-level control
- you need plot types not covered by the grammar and don't want to extend it

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts
- domain: data-visualization, data-science
- platform: python, cross-platform
- tags: ggplot2, grammar-of-graphics, plotting, matplotlib, jupyter, statistical-graphics
