This example displays a stacked line chart of weekly website traffic across five marketing channels, using ECharts with a canvas renderer. The chart includes a title, axis tooltip, legend, and image-saving toolbox feature. Data is loaded from a JSON file containing detailed power plant operations, but the visualization focuses on the static array of channel values for Monday through Sunday. The code initializes an ECharts instance bound to a DOM container, sets a configuration object with stacked line series, and updates the chart on window resize.
