Could you build this?
Partial While an interactive canvas can be scaffolded using libraries like Fabric.js or Konva, building a reliable vector graphic editor with complex scientific illustration assets, parametric connectors, and high-fidelity multi-format exports (PDF, PPTX, SVG) requires non-trivial engineering.
What it would actually take: The frontend would typically rely on Canvas/SVG manipulation engines (e.g., Fabric.js, Pixi.js, or Paper.js) along with a curated library of scientific SVG paths. The hardest parts are layout constraints (smart sticky connectors, port binding), robust bidirectional shape manipulation, and faithful client/server-side conversion to formats like PPTX (using pptxgenjs or backend tools) and vector-perfect PDF printing.
