Mermaid 50K was an early synthetic dataset of 50,000 paired natural-language process descriptions and Mermaid flowchart diagrams, with a matching browser-rendered SVG for every diagram.

This dataset has now been superseded by Mermaid 500k, a substantially larger and higher-quality corpus built from a much more rigorous generation, validation, filtering, deduplication, rendering, and audit pipeline.

Use The New Dataset

Please use:

CoreFidelity/Mermaid_500k

The newer dataset is the one intended for serious training, evaluation, benchmarking, and commercial licensing consideration.

Why This Dataset Is Deprecated

Mermaid 50K was useful as an initial proof of concept, but it is no longer representative of the current dataset quality bar.

Compared with this older 50k flowchart-only release, Mermaid 500k includes:

• 500,000 accepted records
• 500,000 rendered SVGs
• multiple Mermaid diagram types, not just flowcharts
• stronger commercial software/system-design coverage
• richer metadata for slicing by diagram type, domain, difficulty, and template family
• stricter parse/render validation
• exact prompt and Mermaid deduplication
• structural near-duplicate filtering
• text-quality and artifact auditing
• a much more defensible release package for model training and evaluation

Mermaid 500k Coverage

The replacement dataset covers six Mermaid diagram families:

flowchart
er
sequence
class
state
architecture

It is designed for text-to-diagram generation, Mermaid generation, documentation automation, developer-tool training, benchmark construction, and diagram-generation evaluation.

Status Of This Repo

This repo remains available for historical/reference purposes, but it is not recommended for new model training or evaluation work.

If you are evaluating Mermaid generation datasets, licensing data for commercial model training, or looking for a higher-quality corpus, use:
