This stacked bar chart visualizes monthly electricity consumption across multiple accounts, with each bar segmented by account and colored using a categorical scheme. The chart, rendered as an SVG, uses D3's scaleBand, scaleLinear, and scaleOrdinal APIs to map dates, energy values, and account colors, respectively. Interactive hover effects adjust bar opacity, and a tooltip displays each segment's energy value. Data is processed via d3.group and d3.stack to create the stacked series, with the final layout including axis labels and a title.
