便利贴

注释是在图表上方呈现的自由浮动注释 - 为每个注释提供一个位置、一种颜色和一些文本。设置 attachedElement ，一条连接线将注释连接到一个节点，并随着图形的移动而跟踪它。

拖动注释以重新定位它。蓝色音符保持固定在 Carol — 拖动 Carol 并观察连接器跟随。

注释

// Free-floating annotations placed in graph coordinates. `attachedElement` ties a
// note to a node so a connector line tracks it as the graph moves.
const notes = [
    {
        id: 'welcome',
        content: 'Drag me around — I float above the graph.',
        color: '#FDE68A',
        x: -70,
        y: -220,
        width: 240,
        height: 120
    },
    {
        id: 'callout',
        content: 'Pinned to Carol — drag her and I follow.',
        color: '#93C5FD',
        x: 80,
