Usage

---
title: My Post With ECharts
echarts: true
---

Initialize charts using the polling pattern to wait for ECharts to load:

(function poll() {
  if (typeof echarts === 'undefined') { setTimeout(poll, 50); return; }
  const chart = echarts.init(document.getElementById('myChart'));
  chart.setOption(spec);
})();

Pass 'dark' as the second argument to echarts.init() when the current theme is dark to get automatic colour palette switching.
