JBotSim is a multipurpose dynamic network simulator that allows to quickly prototype a distributed algorithm and test its behavior on a set of static or mobile nodes. If mobile, the nodes can be controlled by the mouse or by program.

Chart construction kit for the Java(TM) platform. A small (<100Kb) library and framework for scientific charts and plots. It runs under JDK(TM) 1.1 and PersonalJava(TM) platforms. Renderers for Graphics context, Graphics2D context, and SVG exist.

Lattices and ordered sets visualization tool

JPlotter is an open source math plotter that can draw graphs of arbitrary mathematical functions. Some of the special features are plotting of the derivatives, area calculation, plotting of directional fields of differential equations and plotting of phase and amplitude graph of complex functions.

JProGraM (PRObabilistic GRAphical Models in Java) is a statistical machine learning library. It supports statistical modeling and data analysis along three main directions: (1) probabilistic graphical models (Bayesian networks, Markov random fields, dependency networks, hybrid random fields); (2) parametric, semiparametric, and nonparametric density estimation (Gaussian models, nonparanormal estimators, Parzen windows, Nadaraya-Watson estimator); (3) generative models for random networks (small-world, scale-free, exponential random graphs, Fiedler random fields), subgraph sampling algorithms (random walk, snowball, etc.), and spectral decomposition.

JDMF is a data mining framework written in Java. Main features include: simplicity, flexibility, many algorithms to choose from, many formats of input (e.g. XML, CSV, JDBC, Java beans) and output data (e.g. XML, plain text info, charts).

JCGrid is an easy-to-use tools for real-world grid-computing. It requires only to install Java Runtime and you can easy split your cpu-intensive task among several Workstations/PC/Mac/etc. It includes support for POVRay and MandelGrid as usage examples.

KETL(tm) is a production ready ETL platform. The engine is built upon an open, multi-threaded, XML-based architecture. KETL's is designed to assist in the development and deployment of data integration efforts which require ETL and scheduling

MASQOT-GUI is an open-source, platform-independent application for two-channel microarray spot quality control. Included is a set of tools for gridding, segmentation, quantification, multivariate spot quality assessment and data visualization.

MarDRe is a de novo MapReduce-based parallel tool to remove duplicate and near-duplicate DNA reads through the clustering of single-end and paired-end sequences from FASTQ/FASTA datasets. This tool allows bioinformatics to avoid the analysis of not necessary reads, reducing the time of subsequent procedures with the dataset. MarDRe is the Big Data counterpart of ParDRe (link above), which employs HPC technologies (i.e., hybrid MPI/multithreading) to reduce runtime on multicore systems. Instead, MarDRe takes advantage of the MapReduce programming model to significantly improve ParDRe performance on distributed systems, especially on cloud-based infrastructures. Written in pure Java to maximize cross-platform compatibility, MarDRe is built upon the open-source Apache Hadoop project, the most popular distributed computing framework for Big Data processing.

Graphical front-end for GNU Octave. Edit formulas in mathematical notation. Uses Octave (Matlab clone) as a math engine.

MuLaViTo is a multi-layer visualization framework which allows to visualize relations between multiple graphs in derived applications. Moreover, it provides helpful means like k-shortest path algorithms, running algorithms in a separate thread, ...

A Visual Microcode Simulator for the Classroom

Nested pie chart is for tree visualization. Each node of the tree has a size and color attribute, enabling the chart to be used as a heatmap. Linear arrangement of the nodes in decreasing order of size is an advantage over rectangular heatmaps.

The NEtwork Visualisation Environment is a framework for 3D-visualisation of and interaction with networks, especially communication networks as the internet in both real time and as a simulation tool. Based on JMX/Java3D.

Nexplorer is a web-based phylogenetic browser, used to view and edit comparative data, and ideal for creating publication-quality views in which the tips of a tree are aligned with the rows of a character matrix (e.g., a sequence alignment).

Simulates a biologically diverse tropical island, and the ape inhabitants cognitive processes. For MacOS X, iPad, Windows and Linux. Features a non-polygonal graphics engine and a command-line version

Google Web Toolkit-based tool for publishing user-friendly OLAP views, reports and dashboards. Uses Mondrian OLAP and a relational database as the back-end.

Open2Dprot is an open-source proteomics project for the development of bioinformatic tools for n-dimensional protein expression data analysis of quantified protein expression across multiple samples from research experiments.

PIVOT is a simple yet flexible visualization tool based on Circos (Krzywinski et al., 2009), which offers a fast and aesthetical visualization of data and information. The Protein Interaction Visualization and Observation Tool (PIVOT) was developed specifically for the visualization of protein interaction. It is difficult to spot the proteins that have an interaction when given a large list of proteins but with PIVOT, it is easy to identify the them at a glance. PIVOT displays an image showing all the proteins and draws a connection between proteins that have an interaction.

Azureus Plug-In that allocates the ip adresses of the peers to the country and the city they belong to and visualize that data on a world map or in statistics. This product includes GeoLite data created by MaxMind, available from http://www.maxmind.com/.

This library aims to provide support for D-dimensional images in Java and to enable high-level implementation of algorithms in dimensionally-invariant manner. Major features: the dimensionality and the access to primitive data types are abstracted.

PolyTreeTable is a Swing Component that can display a graph where nodes have multiple parents (polyhierarchy). There is a focus node, a parent tree above, a child tree below, parents expand upwards. It is a JTable derivate with multiple columns.

The Prajna project is a collection of tools and utility classes combining visualization, geographic displays, data fusion, and semantic reasoning into a cohesive toolkit for enhancing information discovery and reasoning.
