ADG: Automatic Drawing Generation
The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a library providing a non-interactive canvas where you can put common CAD entities such as paths, xatches and quotes, to create your technical drawings. The final result can be displayed inside a GTK+ widget or exported to any cairo available format, such as PostScript and PDF documents or PNG and SVG images.

'Asymptote' is a script-based vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. It is a programming language, not just a graphics program, so it can use the best features of both scripts and GUIs. High-level graphics commands are implemented in the language itself, so they can be tailored to specific applications. Labels and equations are typeset with LaTeX for high-quality PostScript output.

Autotrace is a program which converts bitmap images to vector images. It can import images in BMP, TGA, PNM, PPM, PGM, PBM and those supported by ImageMagick, and can output Postscript, svg, xfig, swf, pstoedit, emf, dxf, cgm, mif, p2e and sk

A font editor which can generate fonts in SVG, EOT and TTF format.

'ePiX', a collection of batch programs, creates mathematically accurate fgures, plots, and animations containing LaTeX typography. The input syntac is easy to learn. The output -- vector image files or LaTeX picture-like environments -- is expressly designed for use with LaTeX.

GSEGrafix Heckert gnu.small.png
GSEGrafix is a GNOME application which uses an anti-aliased GNOME canvas for creating scientific and engineering plots. The program is written in C and reads ASCII plot-parameter files and data files. The plot-parameter files contain keywords and corresponding arguments for specifying plot parameters (such as data file names, data file formats, plot type, plot style, axis type, axis labels, etc). GSEGrafix can make rectangular two-dimensional plots (with linear, semilog, or loglog axes), histograms, polar-axis plots, and three-dimensional plots (with linear axes). Three-dimensional plots include points, contour, color, and mesh plots. Data for three-dimensional plots can also be used to create two-dimensional plots using contour lines or color to represent values of a third variable.

Gestalter is a free vector drawing program. Its central element, the Bezier curve, is used as a base part for almost every other object. Complex paths are possible, compound paths can be constructed, grouping of elements is enabled, and everything can be screened by a mask. Adding and deleting of nodes is implemented as well as transformations (translation, rotation, scaling, and skewing).

'Inkscape' is an SVG editor. Supported SVG features include basic shapes, paths, text, alpha blending, transforms, gradients, node editing, svg-to-png export, grouping, and more. It is meant to provide the free software community with a fully XML, SVG, and CSS2 compliant SVG drawing tool.

A free Java chart library. JFreeChart supports pie charts (2D and 3D), bar charts (horizontal and vertical, regular and stacked), line charts, scatter plots, time series charts, high-low-open-close charts, candlestick plots, Gantt charts, combined plots, thermometers, dials and more. JFreeChart can be used in applications, applets, servlets and JSP.

JFreeChart's extensive feature set includes: - a consistent and well-documented API, supporting a wide range of chart types; - a flexible design that is easy to extend, and targets both server-side and client-side applications; - support for many output types, including Swing components, image files (including PNG and JPEG), and vector graphics file formats (including PDF, EPS and SVG); - JFreeChart is free software. It is distributed under the terms of the GNU Lesser General Public Licence (LGPL), which permits use in proprietary applications.

JPIV: Java Particle Image Velocimetry
JPIV is a platform independent, graphical stand-alone application for Particle Image Velocimetry (PIV). PIV is an optical technique for measuring fluid flow velocities. JPIV can be used for multi-pass PIV evaluation, sum of correlation ensemble evaluation, single pixel ensemble evaluation, vector field filtering, calculation of vorticity and other derivatives, third velocity component reconstruction, image and vector field display, vector field statistics and batch processing.
