Shape is a morpho-kinematic modeling and reconstruction tool for astrophysical objects. With this software you can quickly construct 3D model structures and directly compare them with data in order to assist in the interpretation of observations. From such a 3D structure model with a model velocity field and emission properties, it generates images and position-velocity (pv) diagrams, channel maps, light echoes, light curves and one dimensional spectral line shape, to mention a few. Wavelength dependent radiation transfer for line emission and scattering on dust is also possible.

PGFPlots draws high--quality function plots in normal or logarithmic scaling with a user-friendly interface directly in TeX. The user supplies axis labels, legend entries and the plot coordinates for one or more plots and PGFPlots applies axis scaling, computes any logarithms and axis ticks and draws the plots. It supports line plots, scatter plots, piecewise constant plots, bar plots, area plots, mesh-- and surface plots, patch plots, contour plots, quiver plots, histogram plots, polar axes, ternary diagrams, smith charts and some more.

Processing is an open source programming language and environment for people who want to create images, animations, and interactions. Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, there are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production.

NetworkX is a Python language software package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.

On these sites there exist already introductions to Gnuplot, but I want to do it in a slightly different way that concentrates on the way I’m using Gnuplot.
And this way means, that I will present no introduction to the interactive Gnuplot prompt, but will start directly with writing some text files. These files can then be executed by Gnuplot.

If you have astronomical imaging of the sky with celestial coordinates you do not know—or do not trust—then Astrometry.net is for you. Input an image and we'll give you back astrometric calibration meta-data, plus lists of known objects falling inside the field of view.

Dimensions takes important places, events and things, and overlays them onto a map of where you are.

After I’ve covered basic plotting using matplotlib in this part I’ll show you two ways to display histograms of some data.

Welcome to Visual6502.org! Here we'll slowly but surely present our small team's effort to preserve, study, and document historic computers. We aim to present our work in a visual, intuitive manner for education and inspiration, and to serve as a solid verifiable reference for classic computer systems. See our slides for an introduction and some fun images.

EpsTk stands for "Encapsulated PostSript Toolkit". The codebase consists of pure M-files (Octave or MATLAB script files), which may be used to create most standard 2D scientific graphics (line charts, bar charts, polar plots, contour plots, etc.). The M-files write EPS files.

Veusz is a scientific plotting and graphing package written in Python. It uses PyQt (Wiki) and Numpy. Veusz is designed to produce publication-ready Postscript/PDF output. Veusz runs under Unix/Linux, Windows and Mac OS X.
