No - not charts! Graphs are a data structure that are more than just the nodes and edges they contain: from mapping networks to representing arithmetic, from writing chat-bots to inferring relationships, applying graphs to a problem can quite often provide an elegant solution. In this light-hearted and accessible talk, I will cover the basics of graphs as well as go over a few simple but fun examples of this versatile concept.

Thoroughly enjoyable talk. Useful (and relevant day to day) information very well presented!

Very nice explanation of Graphs and Graph Theory. Humorous presentation style with great content

Great talk. Really simplified the complexity of how graphs work. The "open" ending was a bit awkward, but your humor made up for it!

I didn't really enjoy this talk, which sucks to say because I really enjoy talking to you and enjoyed your other talk immensely. Let me tell you why I didn't enjoy this...

I think you were either too nervous or unprepared to present on the topic. It felt as though you were describing something on demand, not because you enjoy the topic. It also felt as though the meaningful introduction to graphs could have been done in half the time.

I feel as though you could entirely drop the Polish Notation section, and show a lot more code about how to create and use graph storage. It doesn't have to be an introduction to a specific graph storage engine, but it could be something like "if you had a graph engine, this is how you would pull some of that data out, and why this would be better than that relational/object engine you're using". I found the "menu" section to be the best part of the talk, because it's the only thing that got close to code. But it happened quickly, right at the end.

Yay graphs.

Good delivery and to a pro-math nerd like me always entertaining. I think the subject and presentation could have failed miserably with any other speaker but Christopher pulled it off with his way of speaking and his humor.

This talk was a good introduction to graphs, where we can find them in existing structures, how they might represent different data types, and how graph-traversal rules can assist with solution finding. Chris brought his delightfully dry humour to ensure the talk lived up to the promise of being light-hearted and accessible.
