# Chartado

> Animated architecture diagram tool that turns plain text into animated, presentation-ready diagrams.

Chartado is a web-based diagramming tool that creates animated architecture diagrams from a simple text-based DSL (Domain-Specific Language). Users describe service connections with arrows and the tool renders them as animated flows.

## Key Features

- Text-to-diagram: Describe flows with arrow syntax (e.g., `User -> API -> Database`)
- Fan-out patterns: One-to-many with curly braces (e.g., `SNS -> {Email, SMS, Push}`)
- Conditional branching: Choice syntax with pipes (e.g., `LLM -> |Tool, Response|`)
- Multi-line flows: Request-response patterns, loops, and convergent entry points
- Animated playback: Messages flow through connections in real time
- Export formats: PNG, WebM, WebP, MP4, GIF, PDF

## Supported Service Types

### AWS Services
Lambda, SQS, SNS, DynamoDB, S3, API Gateway, Kinesis, EventBridge, Step Functions, SES

### AI / Agentic Services

## AI Architecture Diagram Examples

### RAG Pipeline
```
User -> Query Agent -> Vector DB -> LLM -> User
```

### Multi-Agent Router
```
User -> Router Agent -> {Research Agent, Code Agent, Analysis Agent}
```

### ReAct Tool-Calling Agent
```
User -> Agent -> LLM -> |Tool, Response|
Tool -> Agent
```

### Human-in-the-Loop Review
```
User -> Agent -> LLM -> Guardrail -> |Approved, Review|
Review -> Human Reviewer -> Agent
```

### Retrieval + Reranking
```
User -> Agent -> {Vector DB, Memory} -> Reranker Agent -> LLM -> User
```

### Multi-Model Orchestration
```
Orchestrator Agent -> {Claude, GPT, Gemini} -> Aggregator Agent -> User
```

## AWS Architecture Diagram Examples

### Pub/Sub Fan-Out
```
API Gateway -> Lambda -> SNS -> {Lambda Email, Lambda SMS, SQS Archive}
```

### Event Processing Pipeline
```
EventBridge -> { (SQS -> Lambda -> DynamoDB), S3 }
```
