Where is the ngraph command?

Hi Andrei,

I really like your idea to drive visualizations from the command line. But I am missing something to get started. In the readme, there is something written about the ngraph command.

Where can I find that command? What is the source code repo to see how it works? How do i Install that ngraph package?

This repo seems more like a wrapper repo for the project, if I understand correctly.

Thanks a lot!

Hey Patrick,

Sorry about confusion. ngraph is indeed a collection of examples. There is no command line utility. Each example is a standalone application which shows how to use modules from ngraph family. To get started checkout this repository, go to the folder with example you are interested in and run:

npm install
npm start

Ah, thanks for the clarification. I see. Maybe it would make sense to add an overview on the graph modules in the readme.

E.g. some words about:

require('ngraph.forcelayout');
require('ngraph.generators')

I am also not quickly seeing where I load the graph data vs. where the graph is rendered. In the index.html there is a "onLoad" Event handler. But what if I get data from a database as JSON for example. How would the data look like.

Patrick, I am actually trying to keep ngraph modules properly documented. E.g. ngraph.forcelayout, ngraph.generators

Are you talking about specific example?

I see - the idea behind ngraph gets much clearer by looking at the modules. Well, one thing I am still missing is the "mapping" or "bind" step of a data file to a graph, and how this applies to ngraph. One of my difficulties in understanding graphs, is the modeling of references with node and edges. If you have a pointer on that, that would be great (also, how special Graph languages apply to this, e.g. Gremlin or Cypher)
