LiveGraph Java graph framework

LiveGraph is a framework for real-time data visualisation, analysis and logging.
Distinctive features:

• A real-time plotter that can automatically update graphs of your data while it is still being computed by your application.
• Concise and simple point-and-click interface that allows quickly selecting and comparing data series even in applications that output over 1000 series simultaneously.
• Transformation of data series for visual comparison by the virtue of a single click.
  (Linear, logarithm, unit interval, and time-plot transformations).
• The framework is Java-based and can run on any computer system. However, it is easily integrated with applications written in any programming language. Examples and tutorials are provided.
• LiveGraph reads files in a simple CSV-style format. For applications developed in Java, LiveGraph additionally provides an API that handles all data logging and persistency issues.

Skytree Analytics Server

Skytree Analytics Server performs advanced machine learning methods on massive amounts of data. Our approach provides better performance, scalability and predictive accuracy than existing solutions.

Rserve

Rserve is a TCP/IP server which allows other programs to use facilities of R (see www.r-project.org) from various languages without the need to initialize R or link against R library. Every connection has a separate workspace and working directory. Client-side implementations are available for popular languages such as C/C++, PHP and Java. Rserve supports remote connection, authentication and file transfer. Typical use is to integrate R backend for computation of statstical models, plots etc. in other applications.

sigma.js graph Javascript library

sigma.js is an open-source lightweight JavaScript library to draw graphs, using the HTML canvas element. It has been especially designed to:

• Display interactively static graphs exported from a graph visualization software - like Gephi
• Display dynamically graphs that are generated on the fly

hive plots

The hive plot is a rational visualization method for drawing networks. Nodes are mapped to and positioned on radially distributed linear axes — this mapping is based on network structural properties. Edges are drawn as curved links. Simple and interpretable.
The purpose of the hive plot is to establish a new baseline for visualization of large networks — a method that is both general and tunable and useful as a starting point in visually exploring network structure.

knockoutjs data-binding Javascript library

knockoutjs is an declarative data-binding and updating Javascript library that support real-time updates of display data.
