QGIS Labs QGIS Tutorial Labs Home This is a set of tutorial labs for Quantum GIS, an open source geographic information system. The labs are based on QGIS version 1.7.3 (last updated 5/1/2012). I would appreciate hearing comments and suggestions. The labs make use of the following data sets: Field 5 (this is a wheat field located in Central California) Brown's Pond (this is a data set first used in Geographic Information Systems and Cartographic Modeling by C.
How-To: Get Started Protovis uses JavaScript. It helps if you’re already familiar with the language, but it's not necessary; you can pick it up as you go, and learn by example. Here's a minimal but complete visualization that displays “Hello, world!”: You’ll find more off-the-shelf examples included when you download Protovis. (Most of the examples you'll see in the documentation use method chaining to make specifications more concise. Breaking it down: 1. 2. 3.

Examples Enjoy these sample visualizations built with Protovis. For any example, use your browser to view the source or the backing dataset. Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). The Protovis team is now developing a new visualization library, D3.js, with improved support for animation and interaction. D3 builds on many of the concepts in Protovis; for more details, please read the introduction and browse the examples. Conventional While Protovis is designed for custom visualization, it is still easy to create many standard chart types. Area Charts Bar & Column Charts Scatterplots Pie & Donut Charts Line & Step Charts Stacked Charts Grouped Charts Custom Many charting libraries provide stock chart designs, but offer only limited customization; Protovis excels at custom visualization design through a concise representation and precise control over graphical marks.

Protovis 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 free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky.
