What problem does it solve? Drafting patent applications requires standardized technical figures such as method flowcharts and system block diagrams with proper reference numbering, which is tedious to produce manually with drawing tools. ## Core Features & Use Cases - Flowchart Generation: Create method-step flowcharts with decision branches and patent-style step numbering for method claims. - Block Diagram Creation: Build system component and architecture diagrams showing hardware modules, software components, and their interconnections for system claims. - Custom DOT Rendering: Render raw Graphviz DOT code to SVG, PNG, or PDF using multiple layout engines (dot, neato, fdp, circo, twopi). - Use Case: A patent attorney drafting a system claim can define components like an input sensor, processor, and memory, then generate a USPTO-compatible block diagram with reference numbers (10, 20, 30) in one step. ## Quick Start Ask the assistant to create a patent flowchart for your method steps or a block diagram of your system components, and it will generate a numbered SVG or PDF figure using Graphviz.
