Open Source Python Library 'xy': Renders 10M Data Points in 0.01s
techNmak · x · 2026-07-30
A developer introduced xy, a high-performance, open-source Python charting library (Apache-2.0) designed for massive datasets that cause Matplotlib and Plotly to choke.
Key Features:
- Ultra-fast Rendering: Renders 10 million data points as a static PNG in 0.0184s; reaches first interactive render 16-18x faster than mainstream libraries.
- Lossless Detail: Keeps exact source rows accessible on hover and zoom without throwing away data.
- Comprehensive: Supports 15+ chart types including line, scatter, and heatmap, with exports to HTML, PNG, SVG, etc.
The project is currently in early alpha.
