Reflex Open-Sources xy: A Rust-Powered Python Charting Library Rendering 10M Points in 5.4ms
PrajwalTomar_ · x · 2026-07-29
Reflex has open-sourced xy, a Python charting library written in Rust, designed to eliminate the freezing and lagging issues traditional tools face when handling massive datasets.
- Extreme Performance: xy can render 10 million data points in just 5.4 milliseconds, making it 523× faster than Plotly.
- Core Optimization: Instead of drawing every single data point like legacy libraries, xy only draws what fits on the screen, while still allowing users to zoom into any point for exact values.
- Easy Integration: It supports live data streams straight into charts and can be swapped in with a single line of code by developers or AI agents. It is fully open source and available via pip install xy.
