{"version":"1.0","type":"rich","title":"Stacked bar chart","description":"This stacked bar chart displays monthly electricity consumption in kilowatt-hours, segmented by account number. It uses D3.js with the `d3-scale-chromatic` library for color mapping, rendering via SVG and canvas. Data is grouped by read date and stacked using `d3.stack()`, with axes scaled by `scaleBand` and `scaleLinear`. Mouseover interactions adjust bar opacity, and a title tooltip shows the segment’s kilowatt-hour value.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e740c76dc0e748559a8b8b21f5ea5376?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
