A detailed tool for diagrammatic thinking and spatial representation. This tool helps models create and manipulate visual representations of problems. It can be used to develop system diagrams, flowcharts, concept maps, and other visual models. When to use this tool: - System architecture design - Algorithm visualization - Concept mapping and knowledge organization - Pattern recognition in complex data - Spatial problem solving Key features: - Create and manipulate abstract visual elements - Support for multiple visual representation types - Track iterations of visual thinking - Translate between verbal descriptions and visual representations - Generate visual insights from patterns Parameters explained: - operation: The type of action to perform (create, update, delete, transform, observe) - elements: The visual elements to operate on - diagramId: Identifier for the diagram being created or modified - diagramType: The type of diagram (graph, flowchart, state diagram, etc.) - iteration: The current iteration of the visual reasoning process - observation/insight/hypothesis: Verbal reasoning about the visual representation - nextOperationNeeded: Whether another operation is needed in the visual reasoning process
