How do I create a 树状图 chart in JavaScript?

Install with `npm install katucharts.js`, then call KatuCharts.chart(container, { chart: { type: 'treegraph' }, series: [...] }).

Why does my 树状图 chart render as a line chart?

The chart type was not registered. KatuCharts logs "KatuCharts: unknown series type " ", falling back to line" and draws a line chart rather than throwing. Import the module the type belongs to — for example `import 'katucharts.js/bio';` — before creating the chart.

Why do I get "Cannot read properties of null (reading 'appendChild')"?

The container element does not exist when the chart is created. Create the chart after the element is in the DOM: in React that means inside useEffect, not during render.

Why is the chart rendering with zero height?

The container has no height. A div with no content collapses to zero. Give it a height in CSS, or pass `chart: { height: 400 }` in the options.

树状图

type: 'treegraph'

用于层级数据的整齐树形布局。节点绘制为圆形并由平滑连线相连；接受 id/parent 行或嵌套子节点。

KatuCharts.chart('container', {
  chart: { type: 'treegraph' },
  series: [{
    layout: 'horizontal',
    data: [
      { id: 'CEO', name: 'CEO' },

      { id: 'Eng', parent: 'CTO', name: '工程' }
    ]
  }]
});

类型特定选项

选项	描述
`layout`	'horizontal' \| 'vertical' — 树的生长方向。
`layoutAlgorithm`	'tree'（默认）\| 'cluster' — 将叶节点对齐到同一轴。
`link`	连线样式 — { color, lineWidth }。
`marker`	节点圆形 — { radius }。
`levels`	按层级覆盖颜色 — [{ level, color }]。

Common errors

Why does my 树状图 chart render as a line chart?: The chart type was not registered. KatuCharts logs "KatuCharts: unknown series type "<type>", falling back to line" and draws a line chart rather than throwing. Import the module the type belongs to — for example `import 'katucharts.js/bio';` — before creating the chart.
Why do I get "Cannot read properties of null (reading 'appendChild')"?: The container element does not exist when the chart is created. Create the chart after the element is in the DOM: in React that means inside useEffect, not during render.
Why is the chart rendering with zero height?: The container has no height. A div with no content collapses to zero. Give it a height in CSS, or pass `chart: { height: 400 }` in the options.
