This block shows an imaginary virtual network running on imaginary server farms across North America. Brush the graph to see where the physical machines reside. Zoom the map with shift-drag to see the virtual nodes running in those farms and the health of those nodes.
Admittedly, the main purpose for this block is to put dc.js, dc.leaflet.js, and dc.graph.js all in one block.
