vegafusion-runtime

This crate contains the logic for evaluating the task graphs that are generated by vegafusion-core. Task graph evaluation involes:

  • Compiling Vega expression ASTs to DataFusion expressions.
  • Evaluating signal expression tasks
  • Evaluating Data tasks, including transform pipelines. Transforms are implemented against the DataFrame trait provided by vegafusion-dataframe.
  • Pre-transforming Vega specifications by pre-evaluating their transforms and inlining the resulting transformed data.
