This demo shows you how to expose and examine the links between nodes in different combos.

When nodes are combined into a combo, their connections to the rest of the chart are replaced with 'combo links', shown here as dashed lines. Hiding those underlying links reduces chart clutter and keeps the view simple.

Sometimes, however, you may want to reveal the underlying links to show direct connections between nodes across combos.

Clicking on nodes will foreground their direct neighbours and reveal any underlying links. Clicking on a combo node will reveal all the underlying connections from that combo.

Key functions used:

• chart.combo().reveal
• chart.graph().neighbours
• chart.foreground
