# ECharts

> A themeable Apache ECharts wrapper that draws a chart from a plain option object, auto-colors it from your design tokens and theme changes, formats numbers/dates in the current locale, keeps the legend and zoom slider clear of the axes, and supports keyboard navigation. Ported to React from zweiundeins/starbase's `<sb-echarts>` web component (MIT), itself ported from Libretto's `<tco-chart>`.
