Data Analytics Diagram Generator

Quick Start: Define data sources → Declare ingestion/ETL icons → Connect to storage/warehouse → Add BI/visualization → Wrap in ```plantuml fence.

⚠️ IMPORTANT: Always use ```plantuml or ```puml code fence. NEVER use ```text — it will NOT render as a diagram.

Critical Rules

• Every diagram starts with @startuml and ends with @enduml
• Use left to right direction for data pipelines (Source → Ingest → Transform → Store → Visualize)
• Use mxgraph.aws4.* stencil syntax for analytics, database, and storage icons
• Default colors are applied automatically — you do NOT need to specify fillColor or strokeColor
• Use rectangle "Zone" { ... } or package "Layer" { ... } for grouping pipeline stages
• Directed flows use -->, async/streaming flows use ..> (dashed)

Full stencil reference: See stencils/README.md for 9500+ available icons.

Mxgraph Stencil Syntax

mxgraph.aws4.<icon> "Label" as <alias>

Analytics & ETL Stencils

Category	Stencils	Purpose
Query Engine	athena, athena_data_source_connectors	Serverless SQL on S3 data
ETL	glue, glue_crawlers, glue_data_catalog, aws_glue_data_quality, aws_glue_for_ray	Data integration & cataloging
Streaming	kinesis, kinesis_data_streams, kinesis_data_firehose, kinesis_data_analytics, kinesis_video_streams	Real-time data streaming
MapReduce	emr, emr_engine, emr_engine_mapr_m3, emr_engine_mapr_m5	Big data processing (Spark, Hive)
Data Warehouse	redshift, redshift_ra3, redshift_streaming_ingestion, redshift_ml	Columnar analytics warehouse
Search	opensearch_service_data_node, opensearch_ingestion, cloudsearch	Full-text search & log analytics
BI	quicksight	Dashboards & visualizations
Data Lake	lake_formation, s3, glacier, glacier_deep_archive	Governed data lake storage
Catalog	datazone_custom_asset_type, data_exchange	Data governance & sharing
Streaming Kafka	msk, msk_connect	Managed Kafka streaming

Database Stencils

Category	Stencils	Purpose
Relational	aurora, aurora_instance, rds, rds_instance, rds_mysql_instance, rds_postgresql_instance	Transactional databases
NoSQL	dynamodb, dynamodb_table, dynamodb_global_secondary_index, dynamodb_stream	Key-value & document store
Graph	neptune	Graph database
In-Memory	elasticache, elasticache_for_redis, elasticache_for_memcached	Cache & session store
Document	documentdb, documentdb_with_mongodb_compatibility	Document database
Ledger	quantum_ledger_database	Immutable transaction log
Wide-Column	keyspaces	Cassandra-compatible

Connection Types

Syntax	Meaning	Use Case
A --> B	Solid arrow	Batch data flow / API call
A ..> B	Dashed arrow	Streaming / async / CDC
A -- B	Solid line	Bidirectional sync
A --> B : "label"	Labeled connection	Describe data format or volume

Quick Example

@startuml
left to right direction
mxgraph.aws4.s3 "Data Lake\n(S3)" as s3
mxgraph.aws4.glue "Glue\nETL" as glue
mxgraph.aws4.redshift "Redshift" as rs
mxgraph.aws4.quicksight "QuickSight" as qs

s3 --> glue
glue --> rs
rs --> qs
@enduml
