DataMelt (or "DMelt") is an environment for numeric computation, data analysis, computational statistics, and data visualization. This Java multiplatform program is integrated with several scripting languages such as Jython (Python), Groovy, JRuby, BeanShell. DMelt can be used to plot functions and data in 2D and 3D, perform statistical tests, data mining, numeric computations, function minimization, linear algebra, solving systems of linear and differential equations. Linear, non-linear and symbolic regression are also available. Neural networks and various data-manipulation methods are integrated using powerful Java API. Elements of symbolic computations using Octave/Matlab scripting are supported.

AutoAni is a compilation-free adaptive visualization template designed for creating animated bar chart races and similar time-based visualizations using Flash. It focuses on ease of use for beginners by removing the need to install Flash or compile code—users simply prepare their data and images, place them in the same directory, and open the provided SWF file with any compatible player. The template comes with built-in Source Han Sans fonts, ensuring consistent text rendering without requiring users to install additional fonts. It supports smooth and adaptive animation with variable and uniform speed algorithms, making transitions between data states visually clear and accurate. Configuration is handled through simple CSV files, allowing users to adjust layout, speed, positioning, and formatting without editing the source code directly. AutoAni includes modules such as champion bars and champion portraits, with more features planned.

This module provides a Julia-language interface to the free/open-source NLopt library for nonlinear optimization. NLopt provides a common interface for many different optimization algorithms.

PHPlot is a PHP graphics class for creating charts and plots. It works with PHP5 and the PHP GD extension to produce PNG, GIF, or JPEG images. TrueType fonts (TTF) are optional, or built-in GD fonts can be used. The available plot types include: area, bars, line/points, lines, pie, points, squared, stacked-bars, and thin bar-line. Labels, tick marks, plot legend, and X/Y axes and more are all configurable. Images can be imported as a background, multiple graphs can be drawn on one image, and images can be saved to disk or returned to a browser.

Open Source Remote Sensing OSSIM project, pronounced "awesome", will leverage existing algorithms/tools/packages from the open source community in construction of the ultimate Remote Sensing/Image Processing/GIS package. osgPlanet extends OSSIM and Op

pChart is a PHP class oriented framework designed to create aliased charts. Most of the todays chart libraries have a cost, our project is intended to be free. pChart 2.x is now publicly released. You can get it from : http://www.pchart.net

GpsPrune is a java application to view and manage coordinate data, eg from GPS units. With it you can load a variety of text and Xml formats, view the data (in 2d and 3d), edit and convert the data, correlate photos and audio, create charts and more.

SigViewer is a viewer for biosignals such as EEG, EMG, and ECG. SigViewer supports various file formats. Besides viewing biosignals, SigViewer can also create annotations (event markers).

FDS and Smokeview Development has moved to http://fire.nist.gov/fds please update your bookmarks.

A Python interface to the gnuplot plotting program.

Program for viewing X-ray diffraction and control images in the context of data processing by the XDS Program Package.

EasyBMP is an easy cross-platform C++ library for reading and writing Windows bitmap BMP files. No installation, no need for external libraries, small size, well-documented, and simple enough for the novice programmer to start in just minutes!

This is a sophisticated & integrated simulation and analysis environment for dynamical systems models of physical systems (ODEs, DAEs, maps, and hybrid systems). It supports symbolic math, optimization, continuation, data analysis, biological apps...

Software tools for building interactive information visualization applications. Prefuse supports a rich set of features for data modeling, visualization, animation, and interaction for both Java (prefuse) and Flash (prefuse flare).

The PDL module gives standard perl the ability to COMPACTLY store and SPEEDILY manipulate the large N-dimensional data sets that are the bread and butter of scientific computing.

JSynoptic renders information graphically. It can be used as a simple graph plotter, or as a complex run-time monitoring environment. The user sets up shapes (like plots) on graphical pages, and uses data sources (ex: ASCII file) to render information.

OpenGL Mathematics (GLM) is a C++ mathematics library for 3D software based on the OpenGL Shading Language (GLSL) specification.

An open source workbench for chemo- and bioinformatics built on the Eclipse Rich Client Platform (RCP).

The Bulk Meter Flow and Operations project provides a web-based application to manage water meter readings.

Argunet is a client-server software for computer-supported argument visualization (CSAV). Reconstructed debates are visualized as argument maps and can be shared through the Argunet Server.

Graphical user interface for gnuplot to create publication quality figure very quickly. It supports templates for fast formatting of graphics, different plot styles, insets, axis and label options. One important feature is storing metadata in png and pdf files that can be used to reload any graph saved with QuickPlot.

Knitter produces a 3-dimensional model of a knitting pattern. It supports KnitML, as well as a native language similar to that of traditional knitting patterns.

JUNG provides a common and extendible language for the modeling, analysis, and visualization of data that can be represented as a graph or network. New version now available on GitHub: https://github.com/jrtom/jung/releases/tag/jung-2.1

Equalizer is the standard middleware to create parallel OpenGL-based applications. Please visit https://github.com/Eyescale for current development information.
