Import the runtime and evaluate a Vega expression. The embed package bundles the Rust core and is designed for server-side or offline use.

from vegafusion import runtime import vegafusion as vf # Example: evaluate a simple Vega expression result = runtime.eval_expression("2 + 3") print(result) # Note: runtime functions are synchronous in the embed package.
Debug
Known issues
gotchavegafusion-python-embed is a separate package from vegafusion. It bundles the Rust runtime and is intended for embedding in other Python tools. Do not install both vegafusion and vegafusion-python-embed together; they conflict.
fix
Choose one: install vegafusion for client-side use (with WASM), or vegafusion-python-embed for server-side / embedding.
affects: all
deprecatedSome runtime functions (e.g., runtime.pre_transform_spec) that were available in earlier versions are now moved to vegafusion-wasm or vegafusion-client packages. Check if you are using deprecated API.
fix
Use vegafusion-client or vegafusion-wasm for client-side spec transformations. For the embed package, stick to expression evaluation and data transformation.
affects: >=1.4.0
