GraphConnect Europe 2017 Schedule Graph

Yey! It’s that time of the year again! We are full-steam getting ready for the Bi-Yearly Festival of Graphs also known as GraphConnect. There’s another great conference lined up for us. The entire Neo4j crew will be there in full force - and of course we had to create another Schedule graph - just for fun.

A Google Sheet as the main repository

I had to of course start from the schedule on the GraphConnect website, and convert that into a google sheet with all the data. Once I had that, I could add the data pretty easily with this model:


Very simple - but it’s so much nicer when you can make it interactive and load it into Neo4j. Let’s do that. Let’s load that data into this graphgist.

Let’s take a look at what we have now:

Ok - so that looks like a big fat hairball. Not very useful. So let’s try to zoom in a bit, and run a simple query over our graph: let’s find a couple of sessions in Day 1:

match (t:Time)<--(s:Session)--(connections)
return t,s,connections
limit 50

and here’s a sample of the graph:

Let’s do another query:

match path = allshortestpaths( (p1:Person)-[*]-(p2:Person) )
where contains "Morgner"
and contains "Webber"
return path

and display the result

Let’s now look at a link between a person (Jim Webber, of Neo fame) and an Organisation (The Guardian.

match (c:Company {name:"The Guardian"}), (p:Person {name:"Jim Webber"}),
path = allshortestpaths( (c)-[*]-(p) )
return path

and again diplay the result:

Last one for fun: let’s look at the sessions that have more than one speaker:

match (s:Session)-[r:SPEAKS_IN]-(p:Person)
with s, collect(p) as person, count(p) as count
where count > 1
return s,person

and display it:

Just a start…​

There are so many other things that we could look at. Use the console below to explore if you are interested in more.

I hope this gist was interesting for you, and that we will see each other soon.
