Protovis - A graphical approach to visualization

  •        3951

Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is a graphical toolkit, designed for visualization. It retains some of the conceptual simplicity and low-level control of graphical systems by dealing directly with graphical elements.

D3 - A JavaScript visualization library for HTML and SVG

  •    Javascript

D3 is a small, free JavaScript library for manipulating HTML documents based on data. D3 can help you quickly visualize your data as HTML or SVG, handle interactivity, and incorporate smooth transitions and staged animations into your pages. You can use D3 as a visualization framework (like Protovis), or you can use it to build dynamic pages (like jQuery).

vtk-js - Visualization Toolkit for the Web

  •    Javascript

VTK is an open-source software system for image processing, 3D graphics, volume rendering and visualization. VTK includes many advanced algorithms (e.g., surface reconstruction, implicit modelling, decimation) and rendering techniques (e.g., hardware-accelerated volume rendering, LOD control). The JavaScript implementation remain a subset of the actual C++ library but efforts will be made to easily port or compile native VTK code into WebAssembly to better blend both world. The origin of VTK is with the textbook "The Visualization Toolkit, an Object-Oriented Approach to 3D Graphics" originally published by Prentice Hall and now published by Kitware, Inc. (Third Edition ISBN 1-930934-07-6). VTK has grown (since its initial release in 1994) to a world-wide user base in the commercial, academic, and research communities.

Visualization Toolkit

  •    C++

The Visualization Toolkit (VTK) is an open-source, freely available software system for 3D computer graphics, image processing and visualization. VTK supports a wide variety of visualization algorithms including: scalar, vector, tensor, texture, and volumetric methods; and advanced modeling techniques such as: implicit modeling, polygon reduction, mesh smoothing, cutting, contouring, and Delaunay triangulation.

lyra - An interactive, graphical Visualization Design Environment (VDE)

  •    Javascript

Lyra is an interactive environment that enables custom visualization design without writing any code. Graphical “marks” can be bound to data fields using property drop zones; dynamically positioned using connectors; and directly moved, rotated, and resized using handles. Lyra also provides a data pipeline interface for iterative visual specification of data transformations and layout algorithms. Lyra is more expressive than interactive systems like Tableau, allowing designers to create custom visualizations comparable to hand-coded visualizations built with D3 or Processing. These visualizations can then be easily published and reused on the Web. This is the working branch for Lyra 2 and does not contain all functionality. A deployed version of Lyra 1 is available online. For more information, check out the Lyra wiki.

OpenSceneGraph - 3D graphics toolkit

  •    C++

The OpenSceneGraph is an open source high performance 3D graphics toolkit, used by application developers in fields such as visual simulation, games, virtual reality, scientific visualization and modelling. It is based around the concept of a SceneGraph, providing an object-oriented framework on top of OpenGL. This frees the developer from implementing and optimizing low-level graphics calls and provides many additional utilities for rapid development of graphics applications.

bokeh-notebooks - Interactive Web Plotting with Bokeh in IPython notebook

  •    Jupyter

Bokeh is a Python interactive visualization library for large datasets that natively uses the latest web technologies. Its goal is to provide elegant, concise construction of novel graphics in the style of Protovis/D3, while delivering high-performance interactivity over large data to thin clients. These Jupyter notebooks provide useful Bokeh examples and a tutorial to get started. You can visualize the rendered Jupyter notebooks on NBViewer or download the repository and execute jupyter notebook from your terminal.

nuklear - A single-header ANSI C gui library

  •    C

This is a minimal state immediate mode graphical user interface toolkit written in ANSI C and licensed under public domain. It was designed as a simple embeddable user interface for application and does not have any dependencies, a default render backend or OS window and input handling but instead provides a very modular library approach by using simple input state for input and draw commands describing primitive shapes as output. So instead of providing a layered library that tries to abstract over a number of platform and render backends it only focuses on the actual UI. This library is self contained in one single header file and can be used either in header only mode or in implementation mode. The header only mode is used by default when included and allows including this header in other headers and does not contain the actual implementation.

PDF Chain is a graphical user interface for the PDF Toolkit (pdftk). The GUI supports all common features of the command line tool in a comfortable way. PDF Chain generates a command for the PDF Toolkit from the GUI settings and executes it on the system. Therefore the PDF Toolkit must be already installed on the system.

mud - c++ toolkit for rapid development of live graphical apps and games

  •    C++

mud is an all-purpose c++ app prototyping library, focused towards live graphical apps and games. mud contains all the essential building blocks to develop lean c++ apps from scratch, providing reflection and low level generic algorithms, an immediate ui paradigm, and an immediate minimalistic and flexible graphics renderer. mud aims to provide the quickest idioms to build functional and lightweight c++ graphical applications. It tackles the problem of the code you don't want to write, and should not have to write when prototyping an app. One core principle in mud is : don't repeat yourself: we take this aim very seriously and we believe it's a principle that is way too often disregarded.

g2 - G2 (The Grammar of Graphics)

G2 is a visualization grammar, a data-driven visual language with a high level of usability and scalability. It provides a set of grammars, takes users beyond a limited set of charts to an almost unlimited world of graphical forms. With G2, users can describe the visual appearance of a visualization just by one statement. Special thanks to Leland Wilkinson, the author of The Grammar Of Graphics, whose book served as the foundation for G2.
