What the publisher says

From the Semiotic repository's README, as published. We do not edit it. Read it on GitHub

A React data visualization library designed for AI-assisted development.

Start with a small chart component. Add network graphs, streaming data and coordinated views when the task needs them. Structured schemas, diagnostics and rendering evidence help coding assistants implement, check and repair chart configurations.

Work through a complete task: check category totals, maintain a live chart, or correct a published chart. The source task packets identify their build and evidence scope; source availability does not establish installed or deployed parity.

What's New in 3.10.3

3.10.3 fixes coordinated chart colors and histogram boundaries, and reduces repeated work in graph and physics layouts.

partial category-color provider mappings. Legends reflect resolved colors.

  • Linked charts preserve explicit palettes, including network push mode and

builders, projections, and sediment calculations.

  • The bin transform correctly excludes observations outside custom domains.
  • Large physics datasets avoid array argument-limit crashes in scheduling,

sizing computes shared amount ranges once per batch.

  • Mermaid layering avoids repeated queue shifts and sorting; Crucible body

Why Semiotic

Semiotic is a data visualization library for React that combines broad chart coverage with AI tooling. It supports network graphs, streaming data, statistical distributions and coordinated views, with schemas, examples and diagnostics for implementing and checking each task. Check the project's existing dependencies first: extending its current charting library may be the best fit for a small change.

Built for AI-assisted development

Semiotic provides a workflow for generating, checking and repairing chart configurations. The July 27, 2026 evaluation reports model- and task-specific results; it does not guarantee first-try correctness.
