Welcome to this week’s #GraphCast – our fortnightly series featuring what you might have missed in AV media within the wider the world of graphs.

Last #GraphCast, our Managing Editor, Jocelyn Hoppa, stole the video I was going to pick and presented the absolutely amazing Graph Algorithms & Game of Thrones walkthrough video (presented by Amy Hodler and Jennifer Reif), captured at last year’s GraphTour San Francisco.

Catch this week's GraphCast on Euler's formula and graph duality – an interesting graph theory proof

This week – as holiday gift to all of you graph theory nerds out there (including me) – I’ve picked a non-Neo4j and even non-graph database video to highlight in just a small way the incredible math that underlies all graph technology.

(If you’re maybe more normal and don’t love obscure math videos, don’t worry; we’ll return with plenty of other higher-level Neo4j and graph tech videos in the new year.)

Enjoy this graph theory proof of Euler’s formula, explained by intrepid math YouTuber, 3Blue1Brown:



In this video, 3Blue1Brown gives a description of planar graph duality and how it can be applied to a proof of Euler’s Characteristic Formula. I hope you enjoyed this peek behind the curtain at how graph theory – the math that powers graph technology – looks at the world through an entirely different lens that solves problems in new and meaningful ways.
