vis is a JavaScript data visualization library used to render interactive networks, timelines, and graphs directly in the web browser. It functions as a relational data mapper and browser-based charting tool, turning complex structured data into dynamic visual patterns to expose entity relationships. The library provides specialized tools for force-directed network graphs, where relational data is represented as interactive nodes and edges. It also includes an interactive timeline component for plotting chronological events and time intervals on a scalable temporal axis. The project covers b

Interactive open source visualization platform for multivariate dynamic networks.

VivaGraphJS is a JavaScript graph visualization library used to render interactive network diagrams and relational data in web browsers. It features a force-directed layout engine that employs physics-based simulations, using spring and charge models to calculate balanced spatial distributions for nodes and links. The library utilizes a modular rendering architecture that decouples mathematical layout logic from the visual output. This allows for interchangeable rendering pipelines, supporting both vector-based SVG diagrams and hardware-accelerated WebGL rendering for large-scale visualizatio
