The Push to Ban Ransom Payments Is Gaining Momentum
Ransomware costs victims an estimated $30 billion per year and has gotten so out of control that global support for banning payments is gaining momentum.

Readme
Create graphs from your CommonJS or AMD module dependencies. Could also be useful for finding circular dependencies in your code. Tested on Node.js and RequireJS projects. Dependencies are calculated using static code analysis. CommonJS dependencies are found using James Halliday's detective and for AMD I'm using some parts copied from James Burke's RequireJS (both are using UglifyJS). Modules written in CoffeeScript with extension .coffee are supported and will automatically be compiled on-the-fly.
Here's a very simple example of a generated image.
Here's an example generated from the Express project.
And some terminal usage.
To install as a library:
$ npm install madge
To install the command-line tool:
$ sudo npm -g install madge
Only required if you want to generate the visual graphs using Graphviz.
$ sudo port install graphviz
$ sudo apt-get install graphviz
Coming soon ..
Usage: madge [options] <file|dir ...>
Options:
-h, --help output usage information
-V, --version output the version number
-f, --format <name> format to parse (amd/cjs)
-o, --output <type> output format (plain/json)
-s, --summary show summary of all dependencies
-c, --circular show circular dependencies
-d, --depends <id> show modules that depends on the given id
-x, --exclude <regex> a regular expression for excluding modules
-t, --dot output graph in the DOT language
-i, --image <filename> write graph to file as a PNG image
-l, --layout <name> layout engine to use for image graph (dot/neato/fdp/sfdp/twopi/circo)
-b, --break-on-error break on parse errors & missing modules
-n, --no-colors skip colors in output and images
-r, --read skip scanning folders and read JSON from stdin
-C, --config <filename> provide a config file

$ npm test
Complete path in circular dependencies is now printed (and marked as red in image graphs).
Added support for CoffeeScript. Files with extension .coffee will automatically be compiled on-the-fly.
Fixed dependency issues with Node.js v0.8.
Added support for Node.js v0.8 and dropped support for lower versions.
Added ability to read config file and customize colors.
Initial release.
