You will notice that the bubbles in this chart take a while to settle
down. This is because this chart is running a force simulation. You
won't be able to switch to the split view or the combined view while
the simulation for one view is in progress. If you don't wish to wait
for the combined and split simulations to finish you can see the end
results in the
other variant of this chart. That chart also
implements a Voronoi layer for a better hover interaction experience.
