Please join us for the following tech talk:

*Tech Talk**:* Graphs! Visualize maps and data graphs live on Wikipedia *Presenter:* Yuri Astrakhan and Dan Andreescu *Date:* May 14th *Time:* 2100 UTC http://www.timeanddate.com/worldclock/fixedtime.html?msg=Tech+Talk%3A+Graphs+&iso=20150514T21&p1=3915&ah=1

This link shows 21:00 UTC-1. I guess the correct one is http://www.timeanddate.com/worldclock/fixedtime.html?msg=Tech+Talk%3A+Graphs..., isn't it?

Link to live YouTube stream http://www.youtube.com/watch?v=j7DTn9jHnI0 *IRC channel for questions/discussion:* #wikimedia-office Google+ page https://plus.google.com/u/0/b/103470172168784626509/events/cjm55bm8ifohmbpubdbvnvlb1n4, another place for questions

*Talk description: *Thanks to many great contributors, we are proud to present the Graphs https://www.mediawiki.org/wiki/Extension:Graph/Demo... because wiki pages with SVG and PNG images is so last century. Graph extension https://www.mediawiki.org/wiki/Extension:Graph allows content authors to insert a data-defined graph or a map in a wiki page. Graph is described using Vega visualization grammar http://trifacta.github.io/vega/ ( demo http://trifacta.github.io/vega/editor/), and allows very complex data transformations, filtering, and soon even animation & interactivity. Combine that with the power of wiki template parameters and Lua scripting, and the results could be stellar. Up to you really. Vega+d3 gives us a huge list of charting options and maps with numerous projections and ability to highlight individual regions. Lastly, graphs could be rendered either in a browser (more interactivity), or on the server (faster load). Demo will be served.

Special thanks goes to milimetric, krinkle, Brion, and gwicke, without whose help this project would have been a lot harder, and to Vega and other open source teams who build such great libraries. _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
