# Diagram to Code

## Question

Can a model read a technical sketch and produce a useful implementation scaffold?

## System Boundary

This Space focuses on diagram interpretation, not full software synthesis. The output is a starting point a human engineer can inspect and refine.

## Method

The user uploads a diagram and selects a target representation: SQL schema, flowchart-to-Python, UML-to-classes, UI-to-HTML, or general sketch-to-code. A vision-language model extracts the visual structure and generates code in the selected format.

## Technique

This Space demonstrates multimodal program synthesis. The model reads visual structure, translates it into an intermediate interpretation, and then emits code.

The key technical idea is that diagrams are compressed specifications. A model has to recover entities, relationships, arrows, labels, and implied control flow.

## Output

The app returns generated code plus a short explanation of the inferred diagram semantics.

## Why It Matters

Multimodal models are useful when they connect visual reasoning to executable artifacts. This demo shows that bridge directly.

## What To Notice

The explanation matters as much as the code. If the model misunderstood the diagram, the explanation is where the error usually becomes visible.

## Effect In Practice

This pattern can help turn whiteboard sketches, architecture notes, and rough schemas into reviewable engineering drafts.

## Hugging Face Extension

The Space can become a benchmark for diagram understanding by pairing diagrams with expected SQL, Python, or class definitions.

## Limitations

The model can misunderstand ambiguous sketches. Generated code should be treated as a draft and reviewed before use.

## Run Locally

```bash
pip install -r requirements.txt
python app.py
```
