Security Groups Edge Bundling - Original
These are the original scripts used in my original blog post about visualising EC2 security groups.
Unless you really want to run it locally (and do the transforms, etc), you should use this tool as described in my redux visualisation post.
Instructions
You need nodejs to run the script. Once you've extracted the files, run a "npm install" in the directory, you should be able to run "node index.js" and see the output - I was just running "node index.js > data.json" to create my data file. The settings you might need to change are in "extract.js" (which handles getting the data from the API initially): you'll probably want to change the region (currently us-east-1) and the security group filter (currently "AppName").
