SetupVega

Provides a convenient single-import setup for Vega visualization capabilities.

This object aggregates and re-exports all essential types and implicits needed to create Vega visualizations, but does not include a rendering target (e.g., browser, file). Users should import from this object when they want to define Vega specifications and will configure the output target separately.

Exports include:

• Plottable instances for converting data types to visualizations
• vegaFlavour for specifying Vega vs Vega-Lite
• Circe JSON given instances for serialization
• VegaPlot macro for compile-time spec validation
• VegaSpec type for representing Vega specifications
• Circe Json type and json string interpolator for JSON construction
