Mermaid Text-to-Diagram Dataset
Converted and cleaned version of Celiadraw/text-to-mermaid.
Changes from Original
Shape syntax normalization: All @{ shape: ... } syntax (Mermaid v11+ non-standard) converted to traditional bracket-based syntax
NodeID@{ shape: rect, label: "Text" } → NodeID["Text"]
NodeID@{ shape: diamond } → NodeID{NodeID}
All 40+ shape types mapped to their bracket equivalents
Validation: 99.2% valid Mermaid syntax (validated with mmdc CLI)… See the full description on the dataset page: https://huggingface.co/datasets/SpongeBOB9684/mermaid-text-to-diagram.MermaidSeqBench

Dataset Summary
This dataset provides a human-verified benchmark for assessing large language models (LLMs) on their ability to generate Mermaid sequence diagrams from natural language prompts.
The dataset was synthetically generated using large language models (LLMs), starting from a small set of seed examples provided by a subject-matter expert. All outputs were subsequently manually verified and corrected by human annotators to ensure… See the full description on the dataset page: https://huggingface.co/datasets/ibm-research/MermaidSeqBench.text-to-mermaidmermaid-persona-queries
Mermaid Persona Queries (v1)
50 hand-written user queries for evaluating and benchmarking text-to-Mermaid
diagram generation, authored across 5 distinct user personas. Users exist
within a single company spanning many roles (engineering, HR, finance, ops,
support, product, legal, IT) — the dataset varies how people ask, not a
business domain.
Motivation
Real users of text-to-diagram tools do not write uniform prompts. Some paste
truncated meeting notes, some… See the full description on the dataset page: https://huggingface.co/datasets/martincousseau/mermaid-persona-queries.Mermaid_500k

Mermaid Expert Corpus 500k Sample
This repository contains a free public sample of the Mermaid Expert Corpus: a commercial-grade text-to-Mermaid dataset built for companies training, evaluating, benchmarking, or routing diagram-generation models.
The sample includes 1,000 records and their rendered SVGs. It is designed to show the shape, metadata richness, diagram quality, and commercial relevance of the full 500,000-record corpus without exposing the licensed dataset itself.… See the full description on the dataset page: https://huggingface.co/datasets/CoreFidelity/Mermaid_500k_1KSample.Mermaid_50K
Mermaid 50K
Deprecated dataset. This repo is preserved for reference only.The recommended current dataset is CoreFidelity/Mermaid_500k.Commercial licensing inquiries: corefidelity@proton.me
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… See the full description on the dataset page: https://huggingface.co/datasets/CoreFidelity/Mermaid_50K.
