How do I create a rango de área spline chart in JavaScript?

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

Why does my rango de área spline 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.
