Starting today, editors can use *<graph>* tag to include complex graphs and maps inside articles.

Graph tag support template parameter expansion. There is also a Graphoid service to convert graphs into images. Currently, Graphoid is used in case the browser does not support modern JavaScript, but I plan to use it for all anonymous users - downloading large JS code needed to render graphs is significantly slower than showing an image.
Potential future growth (developers needed!): * Documentation and better tutorials * Visualize as you type - show changes in graph while editing its code * Visual Editor's plugin * Animation https://github.com/trifacta/vega/wiki/Interaction-Scenarios
Project history: Exactly one year ago, Dan Andreescu (milimetric) and Jon Robson demoed Vega visualization grammar https://trifacta.github.io/vega/ usage in MediaWiki. The project stayed dormant for almost half a year, until Zero team decided it was a good solution to do on-wiki graphs. The project was rewritten, and gained many new features, such as template parameters. Yet, doing graphs just for Zero portal seemed silly. Wider audience meant that we now had to support older browsers, thus Graphoid service was born.
This project could not have happened without the help from Dan Andreescu, Brion Vibber, Timo Tijhof, Chris Steipp, Max Semenik, Marko Obrovac, Alexandros Kosiaris, Jon Robson, Gabriel Wicke, and others who have helped me develop, test, instrument, and deploy Graph extension and Graphoid service. I also would like to thank the Vega team for making this amazing library.
