Crude demo of a 'layered' force-layout graph.

Run flip() in JS console to switch layers. (You need to change the context fo the chrom dev console to the right iframe first, or use window.frames[0].flip())

This uses the character co-occurence in Les Misérables dataset from the canonical D3 force-layout demo.

The choice of what's in what layer is just based on even/odd-numbered node index. This selection mechanism, and the fact that the graph is very dense, means this might not be the most appropriate dataset to demo the 'layering', but hopefully it gives some hint of its potential.

The intent is that slightly different force-layout rules apply to different layers, giving them structural focus as well as visual.

Click to add nodes! Nodes near the cursor will be linked to the new node.

D3's force layout uses the Barnes–Hut approximation to compute repulsive charge forces between all nodes efficiently. Links are implemented as geometric constraints on top of position Verlet integration, offering greater stability. A virtual spring between each node and the center of the chart prevents nodes from drifting into space.

  description <<-EOS
    tsp is a command-line utility for generating 1x1 pixel PNG files with a given
    background colour and opacity. Due to the relative lack of support for RGBA
    amongst web browsers, it's useful to be able to generate background images
