$ npm install graph-wrangle
For drawing graphs, node-canvas is used which requires Cairo and Pango. For details about setting up node-canvas, see their documentation. To install Cairo and Pango on OS X run: brew install pkg-config cairo pango libpng jpeg giflib.
From a command-line:
`
graph-wrangle style -i examples/data/100nodes.json -k genre_like | \
graph-wrangle layout -a force-atlas2 -t 200 | \
graph-wrangle draw -o my_graph.png -w 600 -h 600
Using a pipeline config file (typically named graph-wrangle.config.json or .js)
`
graph-wrangle pipeline --config graph-wrangle.config.json
See the examples folder for example pipeline config JSON and sample graph datasets.
Note that depending how you installed it, you may need to run bin/graph-wrangle.js instead of just typing graph-wrangle.
Run a pipeline with generated output filenames based on the input filename. Available tokens in the pipeline config json are:
* [name] The input graph filename without the json extension (e.g. mygraph.json becomes mygraph)
* [timestamp] The timestamp when the script was run (YYYY-MM-DD-HHmmss)
Example usage:
`
graph-wrangle pipeline --config examples/pipeline_shared_io.json -i examples/data/100nodes.json
You can specify multiple files to run in succession by passing multiple -i arguments.
`
graph-wrangle pipeline --config prepare-graphs.json \
-i week-31-bundle.json \
-i week-33-bundle.json \
-i week-35-bundle.json
Note that globs are also supported:
`
graph-wrangle pipeline --config prepare-graphs.json -i "week-*-bundle.json"
For later animation, it can be helpful to precompute differences between sequential pairs of graphs. Use the sequence command to do so.
Example usage:
`
graph-wrangle sequence -o sequence.json graph1.json graph2.json graph3.json
With globs too:
`
graph-wrangle sequence -o sequence.json "graph*.json"
