Scientific Diagramming

Two-Level Selector: Subject × Chart Type

Scientific diagramming in SparkLumina is powered by the subject × chart type two-level selector in AISidebar. First, select a subject such as “biology,” “chemistry,” “physics,” or “circuit.” Second, select a chart type—e.g., lab setup, molecular structure, circuit diagram, flowchart, or labeled diagram.

This narrows the AI’s domain so it generates diagrams that follow conventions (e.g., standard circuit symbols, chemical structures, or biology diagrams). The selector reduces ambiguity and improves accuracy.

AI-Generated Lab Setups

For chemistry or biology, request lab setups: beakers, burners, test tubes, pipettes, and safety equipment. The AI produces clean, labeled diagrams suitable for lab reports or teaching. You can ask for specific arrangements (“titration setup,” “distillation apparatus”) and the AI streams the elements onto the canvas.

Molecular Structures and Circuit Diagrams

For chemistry, request molecular structures (Lewis structures, skeletal formulas). For physics or engineering, request circuit diagrams with resistors, capacitors, and ICs. The AI uses the appropriate shapes and symbols from the Excalidraw palette, placed and connected logically.

TTS Narration

Enable text-to-speech (TTS) narration and the AI will describe the diagram as it’s drawn. Labels and annotations are read aloud, helping learners with accessibility or reinforcing concepts through audio. The TTS is synchronized with the streaming visuals—audio and drawings stay in sync.

Real-Time Collaboration

Invite students or colleagues to the same room. They see the diagram being built in real time and can add annotations, questions, or corrections. Live cursors show who is working where, and Socket.IO keeps everyone in sync. Perfect for remote lab instruction or collaborative science projects.
