Bookmarks

This example adds a bookmark system directly in the node template and keeps state in localStorage.

What is specific here

A custom star field (nodeBinding.star = 'id') renders a clickable SVG icon per node.
Clicking the star toggles bookmark state for that node (data-bookmark + bookmarked-node class).
Bookmarks are persisted in localStorage under the bookmarked key.
On add, a floating item is created and animated to the bookmarks row with OrgChart.animate.
On remove, the corresponding bookmark item is deleted from the row.
On init, saved bookmarks are restored and rendered in a top bookmarks row.
Clicking a bookmark item calls center(id) to focus the chart on that node.
