Git-Truck is a tool that provides you with a truckload of visualizations for your git repository, and helps you find out if your project has a good truck factor.

Vega is a visualization grammar, a declarative language for creating, saving, and sharing interactive visualization designs. With Vega, you can describe the visual appearance and interactive behavior of a visualization in a JSON format, and generate web-based views using Canvas or SVG.

Graphics with scientific data become clearer when the colours are chosen carefully. It is convenient to have good default schemes ready for each type of data, with colours that are:

distinct for all people, including colour-blind readers;
distinct from black and white;
distinct on screen and paper;
matching well together.

This site shows such schemes, developed with the help of mathematical descriptions of colour differences and the two main types of colour-blind vision.

Bokeh is a Python interactive visualization library that targets modern web browsers for presentation. Its goal is to provide elegant, concise construction of novel graphics in the style of D3.js, but also deliver this capability with high-performance interactivity over very large or streaming datasets. Bokeh can help anyone who would like to quickly and easily create interactive plots, dashboards, and data applications.

Web tool for guidance in choosing choropleth map color schemes, based on the research of Dr. Cynthia Brewer. Built and maintained by Axis Maps.

D3.js is a small, free JavaScript library for manipulating documents based on data.

Interactive Geometry, plotting, visualization

JSXGraph is a cross-browser library for interactive geometry, function plotting, charting, and data visualization in a web browser. It is implemented completely in JavaScript, does not rely on any other library, and uses SVG, VML, or canvas. JSXGraph is easy to embed and has a small footprint: less than 100 KByte if embedded in a web page. No plug-ins are required! Special care has been taken to optimize the performance.

Thanks guys, google was not able to return any of this apparently. FYI: / / omnigraffle for mac
