Semiotic
React data visualization library for streaming, networks, and AI-assisted development
Last verified:
What is Semiotic?
Semiotic is a data visualization framework that combines React and D3 to build interactive charts, network diagrams, and streaming visualizations. It is designed for developers who want to create data visualizations using React components while leveraging D3's powerful visualization capabilities. The framework provides three main frame types: XYFrame for XY data like line charts and scatterplots, OrdinalFrame for categorical data like bar charts and violin plots, and NetworkFrame for topological and network data like flow diagrams and hierarchical views.
Key features include a streaming push API for real-time data updates, animated transitions for smooth visual changes, full accessibility support, annotations for adding context to visualizations, coordinated views for linking multiple charts, themed CSS variables for easy styling, server-side rendering (SSR) support, and AI-facing tooling designed for machine-readable documentation. The library allows simple charts to be created in just 5 lines of code, making it accessible for quick implementation.
Semiotic is primarily for React developers who need to build data visualizations, data analysts who work with interactive dashboards, developers building real-time monitoring systems that require streaming data visualization, and teams creating network or hierarchical data visualizations. It is particularly suited for projects that need coordinated views where multiple charts interact with each other, and for applications requiring accessibility-compliant visualizations.
