This example displays a liquid fill chart with two nested bubbles representing proportions of 0.6 and 0.3, rendered in a canvas via the ECharts library. It uses the `echarts.init` API with a white theme and the `liquidFill` series type, pulling data directly from an inline JavaScript array. The page loads ECharts and its liquidfill plugin from CDN assets, producing a single interactive visualization within a fixed 900x450 pixel container.
