}]示例
KatuCharts.chart('container', {

{ name:'Clade A', branchLength:0.1, children:[{ name:'sp1', branchLength:0.2 }] }
] }] }]
});类型特定选项

|---|---|
layout | 'rectangular'或'radial'。 |
showBranchLengths / showBootstrap | 显示分支长度 / 自举支持。 |

放射布局
将 layout 设为 'radial'，让树以中心向外展开。
KatuCharts.chart('container', {
series: [{
type: 'phylotree', layout: 'radial',
data: [{ name: 'root', children: [/* … */] }]
}]
});Common errors
- Why does my 系统发育树 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.
FAQ

- Install with `npm install katucharts.js`, import the module with `import 'katucharts.js/bio';`, then call KatuCharts.chart(container, { chart: { type: 'phylotree' }, series: [...] }).
