This repository combines visualizations of major software package managers. This is supposed to be shown at http://2015.cascadiajs.com/browser/

After conference update - video

Friends, you are awesome! I can't express how much I appreciate all your kind words and warm feedback. It really means a world for me. Thank you!

The slides are available here: http://anvaka.github.io/talks/cascadia2015/#/ And links to visualizations are below. Before the links, quick keyboard bindings info:

Very detailed information about what you, and how to use it is available here: Software Galaxies Documentation

Here I just menion most important navigation information.

• One finger touch - move forward
• Two fingers touch - move backward
• Rotate device to control the view port

Each graph is indexed individually, and data is pushed to gh-pages branch of galactic-data.

• Indexed by allbower
• Live demo

• Indexed by allcomposer
• Live demo

• Indexed by allgems
• Live demo

• Indexed by allnpm
• Live demo

• Indexed by allgo
• Live demo

git clone https://github.com/anvaka/pm
cd pm
npm i
npm start

This will start local development sever with auto-rebuild.

This section has detailed instructions about how to use the tool with your own graphs. Before you read any further, if your graph is smaller than 10k nodes, consider using ngraph.pixel or VivaGraph both should be able to provide interactive layout.

If your graphs are larger than this, then keep reading.

First, you will need a graph in ngraph.graph format. The ngraph.graph has detailed documentation about how to create graph, but it also has several loaders from popular graph formats (e.g. dot, gexf)

Now that you have a graph we need to compute the layout.

If your graph is smaller than 200k nodes, consider using ngraph.offline.layout. This module was created exactly for the purpose of the pm project, it is well documented, and should be easy to get started with. You can also read layout.js of all[gems|go|bower] packages to see more examples.

If your graph is much larger than 200k nodes, then consider using ngraph.native - this module is harder to work with (as it requires C++ knowledge), but it is much faster.

The secret GitHub visualization is using ngraph.native.

Once layout is computed, we are ready to visualize. Just save the graph using ngraph.tobinary and store it along with latest positions file (produced by layout) into a folder.

Follow the same folder structure as in galactic-data.

Update the config.js in this repository to point to your data server, and you are ready to explore your own graph.

The last shown visualization was secret GitHub followers visualization. It shows all GitHub users who has more than two followers.

The visualization has more than 1,100,000 nodes, and renders at 60 fps when flying around. The FPS drops when you hover-over nodes to 20-30, This is because we are doing hit-testing, to find what's under cursor.

With this many nodes, it runs well in the browser. Unfortunately it requires more than 1GB of RAM. Which may or may not crash your phone browser - sorry about this.

With all warnings said, here are the links:

• Live demo

Please do not hesitate to provide your feedback or bug fixes. Even if it is something small like fixing a typo - I'd be glad to hear from you!
