Data Mining Fusion: Graphing and Charting

Note: My personal choice fell on Shiny, as that the most flexible front-end for interactive 2-D and 3-D visualization for my purposes ( coupled with R (a language for high performance statistical computing).

Visualization Libraries


free and open source software for statistical computing and graphics (with numerous visualization packages)

Shiny (a notable dynamic visualization extension for R)

ggplot2 (a notable static visualization extension for R)

RStudio (IDE for R)

StatET (Eclipse-based IDE for R)

scatter3d: (downloadable from within R IDE)

matplotlib: /* outstanding */

python, (the author passed away in 2012, regretfully). matplotlib is a python 2D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms. matplotlib can be used in python scripts, the python and ipython shell (ala MATLAB®* or Mathematica®†), web application servers, and six graphical user interface toolkits.


Javascript charting library for jQuery

Highcharts: /* outstanding */

Highcharts is a charting library written in pure HTML5/JavaScript, offering intuitive, interactive charts to your web site or web application. Highcharts currently supports line, spline, area, areaspline, column, bar, pie, scatter, angular gauges, arearange, areasplinerange, columnrange, bubble, box plot, error bars, funnel, waterfall and polar chart types.

Highstock: /* outstanding */ /* free for non-commercial use */

Highstock is solely based on native browser technologies and doesn’t require client side plugins like Flash or Java. Furthermore you don’t need to install anything on your server. No PHP or ASP.NET. Highstock needs only two JS files to run: The highstock.js core and either the jQuery, MooTools or Prototype framework. One of these frameworks is most likely already in use in your web page.



[plugins]:[draggable points]:


a library for making high-quality scientific graphics under Linux and Windows; a library for the fast data plotting and data processing of large data arrays; a library for working in window and console modes and for easy embedding into other programs; a library with large and growing set of graphics.

* 11 November 2013. New version (v.2.2) of MathGL is released. There are speeding up, new plot kinds and data handling functions, new plot styles, masks for bitmap output, wx-widget, Lua interface.

* Javascript interface was developed with support of $DATADVANCE company.

gnuplot interfaces in ANSI C:

gnuplot_i talks to a gnuplot process by means of POSIX pipes. This implies that the underlying operating system has the notion of processes and pipes, and advertizes them in a POSIX fashion. Since Windows does not respect this standard, this module will not compile on it, unless you have a compiler that offers a popen call on that platform or simulates it.

[real time data streams]:


Kst is the fastest real-time large-dataset viewing and plotting tool available (you may be interested in some benchmarks) and has built-in data analysis functionality. Kst is very user-friendly (both the community and the program itself!). Kst contains many powerful built-in features and is expandable with plugins and extensions (see developer information in the “Ressources” section). Kst is licensed under the GPL, and is as such freely available for anyone. What’s more, as of 2.0.x it is available on all of the following platforms: Microsoft Windows, Linux, Mac OSX. Note that KDE libraries are an optional dependency (i.e. you can run Kst without KDE, but you get additional features when running on a platform with KDE). See the “Downloads” section for pre-compiled executables or the sources.

Anti-Grain Geometry(AGG): /*outstanding*//*latest update was in 2007, author might be busy, perhaps it’s time to move the project to github*/

Anti-Grain Geometry (AGG) is an Open Source, free of charge graphic library, written in industrially standard C++. The terms and conditions of use AGG are described on The License page. AGG doesn’t depend on any graphic API or technology. Basically, you can think of AGG as of a rendering engine that produces pixel images in memory from some vectorial data. But of course, AGG can do much more than that. The ideas and the philosophy of AGG are: Anti-Aliasing. Subpixel Accuracy. The highest possible quality. High performance. Platform independence and compatibility. Flexibility and extensibility. Lightweight design. Reliability and stability (including numerical stability).

wxArt2D :

WxArt2D is a library for 2D graphical programming. WxArt2D is build on top of the wxWidgets Library. It is build around a document View Framework, and has several graphical drawing context classes. You can display (multiple and different levels) views of a document filled with a hierachy of graphical objects. Tools allow you to zoom, drag, edit etc. the objects on the view.

wxMaxPlot: http://wxmathplot.sourceforge.net

a library to add 2D scientific plot functionality to wxWidgets. It allows to embed inside your program a window for plotting scientific, statistical or mathematical data, with additions like legend or coordinate display in overlay. Multi-platform: runs everywhere wxWidgets does.

[py plotting tools]:

… might need to use Boost.Python:, a good example of its use:

ComponentOne Chart:

ComponentOne Studio for WinRT XAML includes UI controls for data visualization, layout and input. Based on the ComponentOne Silverlight controls and designed to enhance the rich user experience.


The idea is to provide a pure ansi/iso c++ plot class (called PPlot). Of course no actual plotting can be done in c++. The connection to the graphical world (widgets) is done via an abstract class that you have to implement. The class is called Painter and asks you to implement things like  draw a line from (x1,y1) to (x2,y2) draw a text at position (x,y) calculate width of a text when drawn on screen. (implemented the Painter class in QT (a nice c++ framework) and Zinc (an obscure API used in real time computing).)


C++11 plotting library for console apps

TeeChart Pro:

.NET, Java, ActiveX / COM, PHP and Delphi VCL / FireMonkey controls for business, Real-time, Financial, Scientific and Mobile applications.


Graph-tool is an efficient Python module for manipulation and statistical analysis of graphs (a.k.a. networks). Contrary to most other python modules with similar functionality, the core data structures and algorithms are implemented in C++, making extensive use of template metaprogramming, based heavily on the Boost Graph Library. This confers it a level of performance which is comparable (both in memory usage and computation time) to that of a pure C/C++ library. (Many algorithms are implemented in parallel using OpenMP)


Graphviz – Graph Visualization Software. Drawing graphs since 1988


Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System (via both Xlib and XCB), Quartz, Win32, image buffers, PostScript, PDF, and SVG file output. Experimental backends include OpenGL, BeOS, OS/2, and DirectFB. Cairo is designed to produce consistent output on all output media while taking advantage of display hardware acceleration when available (eg. through the X Render Extension). The cairo API provides operations similar to the drawing operators of PostScript and PDF. Operations in cairo including stroking and filling cubic Bézier splines, transforming and compositing translucent images, and antialiased text rendering. All drawing operations can be transformed by any affine transformation (scale, rotation, shear, etc.) Cairo is implemented as a library written in the C programming language, but bindings are available for several different programming languages. Cairo is free software and is available to be redistributed and/or modified under the terms of either the GNU Lesser General Public License (LGPL) version 2.1 or the Mozilla Public License (MPL) version 1.1 at your option.



Gadfly is a plotting and data visualization system written in Julia. It’s influenced heavily by Leland Wilkinson’s book The Grammar of Graphics and Hadley Wickham’s refinment of that grammar in ggplot2. It renders publication quality graphics to PNG, Postscript, PDF, SVG, and Javascript. The Javascript backend uses d3 to add interactivity like panning, zooming, and toggling.
