Information graphics are visual representations of information, data, or knowledge. These graphics are mostly used where complex information needs a simple explanation, such as signs, maps, journalism, technical writing, and education.

Thus tools are mostly used 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 information graphics.

8 Best Open Source information graphics software

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. In addition, it allows you to enter and manipulate equations and coordinates directly.

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 explore mathematical figures and concepts using the computer interactively and Serves 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, 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 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, 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 an open-source computer program for performing numerical computations.

It provides a convenient command-line interface for numerically solving linear and nonlinear problems and performing other numerical experiments using a language mostly compatible with Matlab.

It is easily extensible and customizable via user-defined functions written in Octave’s language or dynamically loaded modules written in C++, C, Fortran, or other languages.
