**information graphics** are **visual representations of information**, data or knowledge. These graphics are mostly used where complex information need a simple explanation, such as in signs, maps, journalism, technical writing, and education.thus tools are mostly use by computer scientists, mathematicians, and statisticians to ease the process of developing and communicating conceptual information. — Wikipedia

Here is a list of 8 useful open source **information graphics software** to create any kind of information graphics.

### GeoGebra Geometry diagrams tool

**GeoGebra**is**free and multi-platform dynamic mathematics software**for all levels of education that joins arithmetic, geometry, algebra and calculus. It offers multiple representations of objects in its graphics, algebra, and spreadsheet views that are all dynamically linked. It allows you to directly enter and manipulate equations and coordinates. Thus you can easily plot functions, work with sliders to investigate parameters, find symbolic derivatives, and use powerful commands like Root or Sequence.### Kig Geometry diagrams tool

**Kig**is a free and**open source KDE application for Interactive Geometry**. It’s intended to serve two purposes: Allow students to interactively explore mathematical figures and concepts using the computer and Serve as a WYSIWYG tool for drawing mathematical figures and including them in other documents. Kig supports macros and is scriptable using Python. It can import and export files in various formats, including SVG, Cabri, Dr. Geo, KGeo, KSeg, and XFig.### Maxima plotting tool

**Maxima**is a system for the**manipulation of symbolic and numerical expressions**, including differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors. It is based on DOE-MACSYMA and licensed under the GPL. Its abilities include symbolic integration, 3D plotting, and an ODE solver.### sympy computer algebra system

**sympy**is a**Python library for symbolic mathematics**. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python and does not require any external libraries.### EJS JavaScript Template library

**EJS**is an**open source JavaScript Template library**. EJS cleans the HTML out of your JavaScript with client side templates. After EJS gets its rubber gloves on dirty code, you’ll feel organized and uncluttered.### jHepWork multiplatform data-analysis framework

**jHepWork**is a full-featured**multiplatform data-analysis framework**for scientists, engineers and students. jHepWork is a 100% pure Java package with numerical and graphical libraries for data-analysis applications.### FreeMat scientific prototyping and data processing tool

**FreeMat**is a free environment for rapid engineering and**scientific prototyping and data processing**. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source. FreeMat is available under the GPL license.### GNU Octave

**GNU Octave**is a**open source computer program for performing numerical computations**. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It is easily extensible and customizable via user-defined functions written in Octave’s own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.

it is very useful mainly teenagers , bcoz we must identify our own track…………… it helpfull for us.
