*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 [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
