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+&iso=20150514T21,
isn't it?

*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.
