# neo4j-graphviz
Minimal Javascript library/tool for generating *dot* and graphviz renderings from a Neo4j Cypher query.
Uses these libraries
* neo4j-driver
* graphviz
## Command Linse Usage
### Minimal:
`node render.js password`
Will write a graph.jpg based on `MATCH path = (a)-[r]->(b) RETURN path`
### Syntax
```
cat query.cypher | node render.js password [file.png/svg/jpg] [renderer]
```
### Example:
From the [Oscars Graph](http://gist.asciidoctor.org/?dropbox-14493611/oscars.adoc).
```
echo 'MATCH path = (n:Nominee {name:"Meryl Streep"})<-[:NOMINATED]-(a:Nomination)-->() RETURN path' | node render.js '****' oscars.svg neato
```
## Programmatic Usage
see also `express-test.js`
```
var ng = require("neo4j-graphviz");
app.get('/', function(req, res){
var type = "svg";
ng.renderGraph("bolt://localhost","neo4j", pwd, req.param("query"), "neato", type, function(error,data) {
if (error) res.status(500).send(error);
else {
res.type(type).send(data);
}
});
});```
