Back in September I gave a talk at the great JSConfEU 2014. The conference was three days of nerdy Javascript-details - highly enjoyable! My talk was on data-vis on mobile devices and I tried to shed light on some of the gritty details that Moritz Stefaner and I discovered over the various responsive projects we did. It also gave me the chance to conserve my beard in video-form for all eternity.
Enjoy:
