## What it is
Semiotic is a React data visualization library covering charts, network graphs, streaming data, and coordinated dashboards. It ships machine-readable schemas and an MCP server so AI coding assistants can generate correct chart code on the first try.

## Use cases
- render charts in a react app
- visualize network graphs
- build dashboards with streaming realtime data
- let an llm generate chart code from schemas
- create coordinated multi-chart views
- validate chart component props from the cli

## When to choose
- you need react-based visualization including networks and streaming data
- you use ai coding assistants and want schema-backed chart codegen
- you want broad chart coverage in one library

## When to avoid
- you need a non-react framework like vue or svelte
- bundle size is critical and you only need one simple chart
- you need server-side rendering of static images

## Facets
- artifact type: library
- maturity: active

- domain: data-visualization, frontend, web-development, artificial-intelligence
- platform: -
- tags: react, d3, streaming-data, network-graphs, ai-assisted-development, llm-codegen, typescript, nodejs, web-server
