@kbn/agent-builder-visualizations-server

Presentation-owned, server-side visualization generation engine for Agent Builder. It builds a visualization config for the renderer chosen by the caller (Lens or Vega — the agent decides and passes renderer to the create_visualization tool):

• lens/ — the Lens engine (buildLensConfig): chart-type selection, schemas, prompts, and palettes.
• vega/ — the Vega-Lite engine (buildVegaConfig): authors and normalizes a Vega-Lite spec for requests Lens cannot express.
• shared/ — guidance reused by both engines (e.g. ES|QL authoring instructions).
• utils/ — small renderer-agnostic helpers.

Consumed by the agent_builder_visualizations and agent_builder_dashboards plugins.
