## What it is
XY is an extremely fast, interactive, and customizable Python charting library for the web, notebooks, and static exports, built on a Rust core with a GPU render client. It scales from small plots to billions of points by computing only what the screen needs, and supports declarative or matplotlib-style chart composition with Python, CSS, or Tailwind customization.

## Use cases
- plot large datasets with millions or billions of points in python
- interactive charts for jupyter notebooks
- export charts as html png svg or pdf
- build custom web app visuals with python charts
- fast scatter and density plots of big data
- matplotlib-style charting with better performance
- pan zoom and select points in large python charts

## When to choose
- you need to visualize very large datasets (millions to billions of points) interactively
- you want one charting library for notebooks, web apps, and static exports
- you need fine-grained customization via Python, CSS, or Tailwind
- matplotlib performance is a bottleneck for your plots

## When to avoid
- you need a mature, battle-tested library for production reporting today (XY is in alpha)
- you rely on matplotlib's full ecosystem of extensions and third-party integrations
- you need chart types or features not yet implemented in an early-stage library

## Facets
- artifact type: library
- maturity: experimental
- function: data-visualization, charts
- domain: data-visualization, data-science, web-development
- platform: python, cross-platform
- tags: charting, rust-core, gpu-rendering, interactive-charts, notebooks, large-datasets, matplotlib-compatible, alpha, web-server
