Cy2Neo - Tiny Neo4j Cypher Workbench with D3 Visualization

Cy2Neo - Tiny Neo4j Cypher Workbench with custom D3 Visualization

Cy2Neo is a tiny Neo4j query console, in a single HTML-page using client-side JavaScript only.

Neo4j is an open source graph database and Cypher is Neo4j’s graph query language.

Cypher queries are highlighted with CodeMirror.

Graph query results are rendered with D3 using a custom renderer based on neo4j’s browser rendering that is part of this project.

Cy2Neo uses a simple Neo4j HTTP-connector that posts Cypher queries to Neo4j’s transactional Cypher HTTP endpoint using jQuery Ajax requests.

You can try it live here, it should be able to connect to any Neo4j 2.x and 3.x instance that’s accessible from your machine. Just enter the Neo4j-URL, username and password in the boxes on the right side.

Note	I wrote most of it while flying from OSCON 2014 in Portland,OR to Chicago on my way home to Dresden, Germany.

Increase Relationship distance between nodes

@jexp
Thanks for the plugin.
How can we increase the relationship(arrow) length between nodes, with current one distance between nodes is very less, labels in relationship is not clear.

Trying to get graph to plot relationships

@jexp
Thanks for this utility.
I was trying to get it to work against my own dataset ... while it brings back the nodes ... it's not rendering any relationships. Should it be able to handle these? I'm working from the neod3 default branch. This is what I'm seeing.

I altered the cypher query to bring back relationship types, thinking that might work, as per table below, but it doesn't fix the graph.

This is the equivalent call using the built-in neo4j-browser .. which works fine ... even if relationships aren't explicitly specified as part of the RETURN.
MATCH (n:project{id:'xxxxx'})-[:HAS_STRUCTURE]-(o:structnode)-[:BRANCH_OF]-(p:structnode) RETURN n, o, p;

Also, is there a way to control which property field is used for naming the nodes?
Thanks.

Graph resize according to window

How to increase graph size based on the window size. Currently graph size remain fixed even if we seen in full window. Any one has any idea.

Many Thanks

the speed of loading is too slow

is there the same question? how can i solve it?

Can't display the properties when clicking the Node or Relationship

Hi, I tried this, it's very useful, while I found when I clicked any Node or Relationship, it couldn't display the properties of them, will you implement this? :)

License

Hi, thank you for making this, it's very useful! What's the license?

CORS and token based Authorization header

Hi, I wanted to use your POC to manage graph rendering myself but it seems to have a problem (maybe directly in neo4j CORS stuff) when using the last token based authentication method.

To know if Authorization header is allowed to be send in cross-domain ajax request the browser send OPTIONS request without it.

In this case sever respond "You're not authorized".

I think you need to be authorized to know you can use Authorization header so it's a dead end...

Maybe I'm wrong so just show me how to handle this case.

Thanks !

Chrome browser console error 401......!!!؟؟؟

Site without login in a PHP website

Hello,

I want to fork your project, but without login, because I want to invite my friend to view my project at a website because he is not a programmer and doesn't have neo4j installed. I also will introduce to my teacher and classmates, but it is to annoying that my teacher and my classmates have to open neo4j, connect it, use my user and my password.

Similar to http://console.neo4j.org/ (it doesn't need login and password).

Remember I use PHP, I use $client->run('CREATE ...') and $query = 'MATCH ...'. I also would like use this graph (nodes and lines).

I followed https://stackoverflow.com/questions/21506825/using-the-neo4j-server-web-interface-for-visualization-on-a-public-website, but you didn't give good answers and didn't explain, because you didn't give tutorials. And their repository is outdated.

I also tried https://neo4j.com/graphgists/ and https://neo4j.com/developer/guide-data-visualization/#_howto_graph_visualization_step_by_step, and nothing worked.

Graph displays different with neo4j browser

Hi, the workbench is very useful for me. Thanks very much for the contribution. But graph displayed in this workbench is still different from that in neo4j browser. For example, though I have changed the color and the border-width of the node in the neo4j browser, nodes queried from the workbench are still the same with before .In addition, the properties of the node can not display when clicking it just as in neo4j browser. Besides, labels of nodes are not displayed. Can you give me some help? Thanks very much.

Choose which property of the neo node to display

Howdy,

Right now it looks like the 1st property, from the list of properties within a node, is being displayed.
How to make it so a different property is displayed?
i.e. now it's showing the node's Uid, but I want it so show the node's Name.

Many Thanks!
