{"version":"1.0","type":"rich","title":"Electric Bar Chart Using d3.stack","description":"This stacked bar chart visualizes two years of personal electricity consumption across three accounts in a three-family structure, with each bar showing monthly kilowatt-hours segmented by account number. Built with D3.js v7, it uses `d3.stack()` to transform grouped data into stacked series, `scaleBand()` and `scaleLinear()` for axes, and `scaleOrdinal()` with `d3.schemeCategory10` for colors. The SVG rendering includes rotated axis labels, a title, and a legend, with tooltips implemented via SVG `<title>` elements showing per-account usage.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7022e550fada4acaae8833f6150f2072?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
