Visualising a fund manager flow graph with columns and worms

We describe a paradigm for visualising time dependent flow in a network of objects connected by abstract relationships (a graph) by representing time in the third dimension. We show two variants of the paradigm, one in which the elements of the graph are shown as vertical columns of varying width and another which emphasises centrality with bending "worms". We demonstrate these techniques by visualising the movements of Fund Managers within the UK Stock Market in terms of their changing share ownership over time.
