MetaPost

Vintage LaTeX is a repository of twenty standalone LuaLaTeX and MetaPost examples covering period-inspired scientific-paper typography, engraved plates, diagrams, charts, tables, and mathematical illustrations. The examples are maintained as independently compilable source files, with build scripts for producing the output; they use LuaLaTeX for document pages and MetaPost, including the external fiziko library, for several figures. The collection demonstrates historical ligatures, old-style figures, warm paper and ink colors, hatching, computed optical rays, generated logarithm tables, star charts, and other mechanisms while retaining diagram labels as searchable text in the resulting vector PDFs. The source, prose, and generated examples are licensed under CC BY-SA 4.0; fiziko is a separate GPL-3.0 dependency.

Diagram Design is a diagram-generation skill for Claude Code, Codex, Factory Droid, and Pi. It produces self-contained HTML and SVG diagrams through 39 editorial visual types, including architecture, flowchart, sequence, state-machine, data-flow, timeline, Sankey, Wardley map, kanban, user journey, deployment, dependency graph, UML class, story map, and database-schema diagrams. It can read a website to match its brand, and can redraw draw.io or Mermaid sources at a selected format, size, and detail level. Its semantic system patterns describe behavior separately from layout, so queues, policy traces, and trust boundaries can use an existing diagram type without adding new layout types. The repository supplies each type in minimal-light, minimal-dark, and full-editorial variants. Static HTML is the default; optional accessible motion is available for ordered explanations. The diagrams require no build step, JavaScript, or external image dependency.

doc7 is an open-source document-to-Markdown tool that converts PDFs, Office files, scans, screenshots, charts, formulas, and diagrams into AI-ready Markdown using an OpenAI-compatible multimodal vision model. It renders and understands complete pages rather than relying on character extraction, preserving text, tables, formulas, chart and diagram relationships, image meaning, and visible UI state; the video also describes page-level retry and resume. The model can run locally through LM Studio or Ollama or through a remote endpoint, with no required OCR stack or document-processing service. The same binary provides an interactive CLI, batch processing, model checks, MCP support, a Go SDK, and an asynchronous HTTP service, with installers for macOS, Linux, and Windows.

markdown-graphs is a collection of React components for ASCII-style tables, charts, and diagrams in MDX. It provides more than 30 graph components, including tables, bar charts, sparklines, heat maps, Gantt charts, timelines, trees, and flow diagrams. Components render inside dashed frames using text glyphs and blocks rather than SVG, with optional single-, dual-, or three-accent palettes. The project distributes source files through a shadcn registry: users can add individual components or the full collection to an existing shadcn project, then import them locally. It is not an npm package and requires an existing shadcn project and Motion. The repository is licensed under MIT.

A Visual Studio Code extension for editing Markdown in a document-like interface, with two-way editing, heading support, and table formatting alongside preview.
