vl-convert-python

vl-convert-python is a dependency-free Python package designed for converting Vega-Lite chart specifications into various static formats, including SVG, PNG images, or equivalent Vega chart specifications. It functions by wrapping the underlying `vl-convert-rs` Rust library, which embeds the Vega-Lite and Vega JavaScript libraries within a v8 runtime, making it self-contained without external browser or Node.js dependencies. The current version is 1.9.0.post1, released on January 21, 2026, and the project demonstrates an active development and release cadence.
