createDiagramAction
Replace the canvas with a clean diagram. Every node is rendered as a native Excalidraw circle; use labels and semantic colors to distinguish roles. For a flow, connect each earlier step to the next step (from → to), so the canvas orders it correctly. For a concept map, connect related concepts and label each arrow with the relationship, such as 'causes', 'uses', 'depends on', or 'is part of'. When a concept benefits from a visual, call searchImages first and put the selected HTTPS result in that node's image.src with a concise alt or caption. Connectors are automatically given spaced anchor slots and routed with right-angle waypoints so they do not touch node frames. Use fromPosition and toPosition when a connector must leave or land on a specific node side.

}updateDiagramAction
Replace the current structured diagram with a complete revised diagram. Preserve node IDs when updating existing concepts. Every node renders as a native Excalidraw circle, while labels and semantic colors communicate meaning. Keep flow arrows directed from the earlier step to the later step, add labels to show meaningful concept relationships, and specify connector sides when the visual landing point matters. Use searchImages before adding a supporting visual and attach the selected HTTPS result through node.image. Connectors use spaced anchor slots and clean right-angle routes with whitespace around circles.

}addNodeAction
Add one labeled node to the current diagram. The renderer uses a native Excalidraw circle for every node; use the label and color to communicate whether it is a process, entity, decision, or outcome.

}searchImagesAnswer
Search Wikimedia Commons for a relevant, reusable teaching visual. Call this before createDiagram, updateDiagram, or addNode when an image would make the explanation easier to understand. Use a concise subject query, then attach one returned HTTPS url to node.image.src. If no result is useful, continue without an image.

}connectNodesAction
Add a directed arrow between two existing diagram nodes. Use from → to for sequence or dependency direction: 'from' happens first or influences 'to'. Add a concise label to explain the relationship when useful. Connectors are routed with clean right-angle waypoints and spaced anchor slots so they stay away from circle frames. Choose fromPosition and toPosition (top, right, bottom, or left) for exact connector landing sides; omit them for automatic routing.
