A simple exercise with cola.js. A node-link diagram is displayed, based on positions computed by cola's fast-converging constraints-based layout algorithm. Handling of more than one connected component, node dragging and non-overlapping constraints are also shown.
Compare with a similar example using native d3.js force-directed layout.
