Alchemy.js - Graph Visualization for the Web

[Huston Hedinger]

Hi Everyone,

There seems to be a lot of questions about open source technologies for building graph/network visualization apps.  I wanted to make you aware of our application Alchemy.js.

Alchemy makes it easy to create graph viz apps with search, filtering, and other features completely through configuration.  e.g.

`Alchemy.begin({some_config});`

You can find the website for Alchemy.js here, the docs are here, and the repo is here.

We are heavily considering out of the box support for Neo4j if the community feels that there would be value in it.  Feel free to let us know!

It took me only a little time on my flight from PDX to ORD to implement cy2neo a browser-only Cypher console with Alchemy.js visualization after I learned about it at OSCON in beautiful Portland.

Looking forward to add edit functionality to it.

One thing that's a concern for my application is security -- and I doubt that Neo4j will ever have the right kind of security for user-level access.  This is often the case -- because the application's visibility rules are typically domain-specific.

Most web apps I know of implement their own security (RBAC or similar) - and don't allow direct access to the database because of security concerns.

The other aspect that my app has which is a more general problem with rich and complex graphs is that it's hard to know what to present that would give insight -- and not make the user run for the door with a headache because of the complexity of the display.

If you have ideas on how to solve these things in general that would be awesome!

Right but none of those was ever focus for this demo.

We should take that topic into a different thread.

For your second question there was an excellent post on that topic lately:

I was just trying to encourage the folks at Alchemy.js to consider addressing them - not intending to criticize the demo.

Sorry if it came across otherwise.
