Adobe Illustrator  Professional standard software for creating original vectorbased graphics. Includes powerful drawing tools and brushes. The ai file format is a common vector format for exchange and its feature set allows creation of complex vector artwork. Illustrator imports over two dozen formats (including PDF and SVG). Of particular use to data visualization is importation of SVG, or scalar vector graphics, which is an W3C recommendation, and is often exported from other programs.

Adobe Photoshop  Photoshop is a comprehensive photo editing tool produced by Adobe Systems. Users can manipulate photos, graphics, and other raster images using a variety of tools and predefined filters. Photoshop also allows users to record specific photo editing steps, which allows for automated batch processing. Photoshop is available as a standalone product, but is also part of Adobe's "Creative Suite" family of products. Photoshop Extended is an enhancement to Photoshop, and provides for enhanced 3D creation and editing.  No programming  Costbasis  
Asymptote  Asymptote is a vector graphics language that can be used for technical drawing. Being a language, it gives ultimate control to the user. Typesetting of labels and equations is done by LaTeX, which produces highquality PostScript output. It provides a portable standard for typesetting mathematical figures and generates output in PostScript, PDF, SVG, or 3D PRC vector graphics.

GIMP (Graphical Image Manipulation Program)  GIMP is an open source and free alternative to Photoshop. It is intended for use with Raster graphics, and can be used for creating new images, retouching photographic images and converting files to different file types. Gimp supports most image file types as well as other graphical image manipulation program file types. It is also possible to create custom scripts to automate a variety of tasks.

Google Charts  Google Charts is a combination of two application programming interfaces (APIs), Google Chart API and Google Visualization API. Google Chart API creates static visualizations of data and embeds them into webpages. Some HTML programming experience is recommended. Available visualization types include standard scatter, line, bar, pie, and box charts as well as Venn diagrams, dynamic icons or callouts, formulas, and connectivity graphs. In addition, maps can be made and embedded into webpages.  Basic programming skills  Free  For comparison of the two APIs: http://code.google.com/apis/charttools/docs/choosing.html 
JMP  JMP is a desktop software package designed by SAS for dynamic data visualization and statistical data exploration. JMP includes an interactive graph builder that supports a wide variety of two and threedimensional graph types, and statisical reports are displayed along with plots for assessment and interpretation. Data can be loaded into JMP from common desktop file formats (e.g. text and spreadsheet files), as well as from a database or SAS server, and reports and visualizations can be exported in HTML, PDF and Adobe Flash formats for displaying and sharing results. JMP also integrates with the full SAS statistical software package to support more comprehensive analyses.  No programming  Costbasis  Schlotzhauer, S. 2007. Elementary Statistics using JMP.

Keynote  Keynote is an Apple's presentation software. Presentation software is primarily used for composing "slides" for presentations. Emphasis is on graphics and animation. Keynote files can be saved as PowerPoint.  No programming  Costbasis  
MATLAB  MATLAB is an interactive data analysis and visualization environment that can be used to perform computationallyintense operations on large data sets efficiently. MATLAB also provides a high level programming language that supports rapid development of workflow scripts and Graphical User Interface applications to automate repetitive tasks. A wide variety of disciplinespecific software libraries, called toolboxes, are available from the publisher or user communities to extend the capabilities of the base program (e.g. statistics, curve fitting, image analysis and mapping). MATLAB programs can also leverage existing code written in Fortran, Java or other languages and source code is provided for most functions, allowing endusers to extend or customize routines for specialized analyses.

NodeXL  NodeXL is a free, opensource template for Excel 2007 and 2010 that lets you enter a network edge list, click a button, and see the network graph, all in the Excel window. You can customize the graph’s appearance; zoom, scale and pan the graph; dynamically filter vertices and edges; alter the graph’s layout; find clusters of related vertices; and calculate graph metrics. Networks can be imported from and exported to a variety of file formats, and builtin connections for getting networks from Twitter, Flickr, YouTube.  No programming  Free  
Octave  GNU Octave is a highlevel language, primarily intended for numerical computations. It provides a 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 may also be used as a batchoriented language. Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differentialalgebraic equations. It is easily extensible and customizable via userdefined functions written in Octave's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.
