This demo shows how to display a right-click context menu with selected actions for chart elements.

When invoked on the chart background, the context menu shows an option to select all nodes. When invoked on a node or link, the context menu offers the options to select all the neighbours of a clicked item, or to unselect all items.

Generally it is good practice to offer only a small number of options.

Key functions used:

• Chart Events
• 'view-change'
• chart.graph().neighbours
