Exploratory Graph Visualization

  • This location is shown only to members

Graphs are abstract representations of a group of nodes connected by links. Graphs can be challenging to visualize, because even small networks can have high complexity.

This meetup will follow an experimental format to organize the event. Rather than setting an agenda ahead of time, we'll work as a group to brainstorm issues and opportunities related to exploratory and graph visualization. There will be multiple spaces set up for discussion and working groups to dig into these issues.

There will be no speaker or formal structure to this event, aside from initial agenda-setting. Please come prepared to be an active participant and review the meeting process.

d3.js is a great starting place for interactive graph exploration with examples of dendrograms, hive plots, chord diagrams, adjacency matrices, and force-directed layouts. Experience with visualization software like Graphviz and Gephi is also relevant, as well as experience with graph databases, scripting languages and real-world problems related to graphs.

Food and drinks will be sponsored by Dynaprice, delivering data services to Fortune 500 companies. They're looking for a developer with graph visualization experience, so contact them if you're interested.

Thanks to Twitter for hosting the event! They're hiring!

    Good brainstorm of visualizations/techniques to communicate better. I liked the break out groups, i got a chance to hear how other people were using d3 as well as tell my side of the story. Looking forward to future meetups

    I don't use d3 that much yet, so it was a little tough being a newcomer. But all-in-all the discussions were mostly conceptual which I was able to participate in more.

    this what happens when you put a bunch of self-important self-aggrandizers in a room with no agenda.

I started the group because there wasn't any other type of group like this. I've met some great folks in the group who have become close friends and have also met some amazing business owners.
