This chart displays multiple area and line series for time-varying energy data, grouped by stream name. It uses D3 v5 to scale time and linear axes, and renders SVG paths. The visualization employs `d3.area` for filled regions and `d3.line` for stroke lines, with colors assigned via `d3.scaleOrdinal` and `schemeCategory10`. Gradient definitions and clipping paths are added to highlight the area series. The data consists of energy readings with timestamps and stream identifiers.
