Node setter is now fluent.
Fixing `for in` loops
You can use node.set('attr1','').set('attr2','');
`npm install node-graphviz` --> `npm install graphviz`
Fixed so it can be installed on v0.8. Please bump version & update the NPM repo :)
…d on node v0.8 without warnings/errors.
Hi! I fixed some calls to "sys" for you!
…h node v0.8
graphviz.js: Don't require the 'sys' module.
It's not used and it causes a deprecation warning with node.js 0.6 because the module has been renamed to 'util'.
