And just like that, August is almost over! Everyone is returning from their August vacations (or maybe staycations), the kids are returning to school (whatever that might look like in your part of the world), and our minds are naturally returning to our work with the beginning of the new season.
As usual, things have been quite busy and exciting among the Neo4j community! In this week’s Twin4j, we will get to see something that we don’t see that often: Neo4j powering a virtual reality documentary experience on Steam VR! We have a few different posts this week about using the AuraDB Free tier to do things ranging from the analysis of our favorite movie graph to a full-on recommendation engine for a community-owned music network. We also have an iOS app created for looking at your personal “Six Degrees of Kevin Bacon” (also known as the small-world concept) through your social media connections.
I also wanted to highlight that we are re-running the NODES 2021 workshops the week of September 13, 2021. If you missed any of these two-hour, hands-on workshops, now is your chance to see them again!

Nigel Small – This Week’s Featured Community Member
You may not know whether or not you have interacted with Nigel, but if you work with any of the Neo4j drivers – and particularly if you use the community-supported py2neo Python driver – then you have interacted with him quite a bit! Nigel is the author and maintainer of this very popular, open-source Python driver, which celebrated its 10th anniversary this year. According to the pypi.org statistics as of the writing of this week’s post, py2neo has over 1,000 stars and over 200 forks on GitHub. It also averages about 110k downloads per month.
In addition to his work on py2neo, Nigel has been an employee at Neo4j since 2014, both leading the Drivers team and as a member of the AuraDB team. Nigel released version 2021.2.0 of py2neo on August 24, 2021, which will be the last significant release for a while as he moves on to new opportunities. Nigel, we will miss you tremendously and wish you all the best in your new role!
Neo4j Training Series September
After the great success of our last training week ahead of NODES 2021, we’re inviting you to join our next week of training in September. Starting Monday, September 13, we’ll be hosting a different two-hour workshop every day. We will start with an Introduction Session, where we show you what graph-based problems look like, and continue with an Overview to Neo4j AuraDB and interact with your (first?) graph database in the cloud. The series continues with Neo4j Bloom and how to best visualize graphs. Finally, we learn how to Build APIs with Neo4j GraphQL Library before we finish the week by Creating a Knowledge Graph.
We are looking forward to having you join us on any (or all) session throughout the week!
“A Clever Label” Released on Steam VR
There was a great announcement from one of the participants in the Neo4j startup program. Michela Ledwidge, co-founder of Sydney studio Mod, has reported in the Discourse community forums that her work in immersive data storytelling is now available on the Steam VR platform. In particular, Mod has released a documentary experience that allows audiences to find hidden relationships between anti-equality lobbyists, Australian politicians, and international organizations. Powered by Neo4j, the audience is able to interact in virtual reality with the data that goes beyond a fixed narrative, eliminating the one-way communication of a traditional documentary.
First Proof of “Six Degrees of Separation”
What began as a conversation with friends about COVID resulted in an in-depth review of the “Six Degrees of Separation” theory. Isa Yeter breaks down this small-world concept in a new blog post where he discusses an app that he developed called Pathica. The purpose of Pathica is to illustrate your own personal “friend of a friend” network on social media and create your own six degrees to Kevin Bacon. Pathica is presently available for download on the Apple App Store with an Android version reported to be coming soon.
Resotrack: Exploring the Resonate API with Django-Neomodel on AuraDB
Resonate, the community-owned music network, was in need of a solution that could turn tags associated with songs, albums, and genres into recommendations for music. To do so, they used Neo4j to suggest relevant tracks within each tag based on track popularity for their entire music catalog. This is built using Django-Neomodel and deployed on AuraDB Free and Heroku. Cristina Escalante walks us through the setup and code for how to do it.
Subgraph filtering in Neo4j Graph Data Science library
In his latest post, Tomaz Bratanic takes a look at one of the newer features of the Graph Data Science library: working with subgraphs. Working with a data set he created of Harry Potter characters and their interactions, Tomaz demonstrates how to create a subgraph. He then shows how subgraphs can be used as part of an efficient workflow that skips over the creation of unnecessary additional in-memory graphs or writing intermediate results back to the database.
Get Up and Running with Neo4j on Sandbox or AuraDB Free Tier
Lju Lazarevic describes how to get up and running with Neo4j, either with Neo4j Sandbox or the Neo4j AuraDB Free tier, using one of her favorite graphs: the basic movie graph. This post is a great start for beginners on either platform. It’s also a concise walk-through for seasoned users of Neo4j Sandbox about how to get started with the Neo4j AuraDB Free tier.
