KmPlot is a mathematical function plotter. It has built in a powerfull parser. You can plot different functions simultaneously and combine their function terms to build new functions. KmPlot supports ... [More] functions with parameters and functions in polar coordinates. Several grid modes are possible. Plots may be printed with high precision in correct scale. Features * powerful mathematical parser * precise metric printing * different plot types (functions, parametric, polar) * highly configurable visual settings (plot line, axes, grid) * export to bitmap format (BMP and PNG) and scalable vector graphics (SVG) * save/load complete session in readable xml format * trace mode: cross hair following plot, coordinates shown in the status bar support zooming and more.

KAlgebra is a calculator with symbolic and analysis features that lets you plot 2D and 3D functions as well as to easily calculate mathematical expressions.

This is another library for creating and manipulating graphs. There is simply no other graph library out there which can be handle graphs of the size the author is confronted with efficiently. ... [More] Whenever possible igraph tries to be also user friendly and portable. igraph started as an additional package to the GNU R statistical environment, and still some functions which are hard to implement in C are available only in R (like interactive graphics). Most functions are however now written in C and they can be compiled without R as a separate library. [Less]

FuzzPy is a library for fuzzy sets, fuzzy graphs, and general fuzzy mathematics for Python.

Python-based tools and GUI for fast and intuitive graph works

WikiPlot is a plotting extension for MediaWiki, written completly in php. That will enable users to plot graphs from a mathematical expression, like x^2+4. The project has been released, and we ... [More] haven't planed much further development, but if you have any bugs, or feature request feel free to contact us. We're not completely closing development, and sometime in the future we might create a version 2.0... StatusThe project is currently kind of dead, or lets just say not in active development. Main developers got other things to play with. But the code should be stable, feel free to submit patches, comments, bug reports, etc. any feedback is welcome. [Less]

VEGAVEGA is both a program for visualizing algorithms, as well as a library of Graph classes that can aid the programmer in the development of their own algorithms. LibraryThe VEGA library is ... [More] currently under development, but so far has a large set of base classes to work with. The code utilizes the Java Generics framework which allows for compile-time type checking, so as to prevent class cast errors. This is not a requirement for the developer, but is highly recommended. The code consists of a series of base classes that can be used to construct more complicated structures. All forms of Graphs, whether they be Trees or Networks, extend the base Abstract Graph class, which utilizes the Graph interface also included in the code. It should be noted that almost every class included in VEGA has a corresponding interface that allows for custom development of classes to meet specific requirements and expectations. VEGA ApplicationThe VEGA Application is a tool that is meant to help users see how an algorithm or data-structure works by visually representing it using Graphviz. The reasoning behind the development of the application is that it is far easier to understand how something works when one moves beyond abstract mathematical notation and is able to see working demos. VEGA has been developed such that it is not able to just represent a handful of algorithms and data-structures, but rather any algorithm or data-structure that adheres to some basic conventions. By implementing some basic methods, a user is able to take existing code of an algorithm or data-structure and output the necessary information to VEGA for representation. Current Algorithms and Data StructuresWe currently have implemented a handful of algorithms and data structures, and more are on the way. As of July 10, 2008, we have the following: Fibonacci Heaps Red Black Trees Dijkstra's Algorithm 2-OPT (TSP Algorithm) Nearest Neighbor Algorithm Heap sort Binary Search Tree Prim's Algorithm We anticipate having Thin and Thick heaps implemented by the end of summer 2008.

The purpose of the graph editor is to make it fast and easy to draw graphs, perform some simple operations on graphs and export graphs to useful file formats etc. The graph editor can also be used to ... [More] study the structure of graphs by moving it’s parts around in an intuitive way. The program is developed in the programming language Java and thereby platform independent. The program uses a lot of open source software libraries. In particular it uses the JGraph which is a software library for graph manipulation. Installation Contribute Contact [Less]

Introductionflashgraph provides a set of ActionScript 3 components and classes for quickly parsing and evaluating functions of multiple variables and graphing functions of one variable. Here are ... [More] some basic examples of what flashgraph can do: ExprCalculator is a basic "calculator" that can evaluate functions of 2 variables. GraphDemo shows some keyboard and mouse interactions with a graph. Magnify is an example of a simple educational math applet designed to elucidate the concept of the derivative. How do I get it?The latest release is available in a downloadable package to the right of this text or on the Downloads page. flashgraph is currently under the GPLv2 license. What next?The API documentation is now up (and is also available in the doc directory of the distribution). There is also some tutorial material on the Wiki: GettingStarted contains installation instructions and other preparatory information. ExprExamples has examples of the expression parsing library. GrapherExamples shows some basic uses of the grapher component. The examples linked to above are included in the distribution in the examples folder. Their source should is heavily commented and should prove helpful. If you run into a problem (which will undoubtedly happen), feel free to drop me a line, leave a comment on the Wiki, or submit an issue. Please see the FuturePlans page before requesting a feature.
