## What it is
Lets-Plot is a multiplatform plotting library based on the Grammar of Graphics, offering a faithful port of R's ggplot2 to Python and Kotlin. It supports notebooks, JVM/Swing/JavaFX apps, Kotlin/JS, and Compose Multiplatform, with geospatial visualization and customizable tooltips.

## Use cases
- create ggplot2-style plots in Python
- plot data in Jupyter or Kotlin notebooks
- embed charts in Compose Multiplatform apps
- visualize geospatial data with geocoding
- add plotting to JVM Swing or JavaFX applications
- make statistical graphics in Kotlin

## When to choose
- you want ggplot2-like grammar-of-graphics plotting in Python or Kotlin
- you need plots across notebooks, JVM, JS, and multiplatform apps
- you need geospatial plotting with geocoding support

## When to avoid
- you need interactive dashboards or BI-style tools rather than statistical graphics
- you prefer matplotlib-native or web charting ecosystems like Plotly or ECharts

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts, geospatial
- domain: data-visualization, data-science, cross-platform
- platform: python, jvm, browser, cross-platform
- tags: ggplot2, grammar-of-graphics, jupyter, kotlin-multiplatform, compose-multiplatform, notebooks, plotting, desktop
