This visualization plots hourly kilowatt readings from the MFRED dataset against time, with each of the 26 generator units (AG01 through AG26) colored distinctly by category. It uses the Vega-Lite API, registered with vega and vega-lite, to render point marks on an SVG canvas. The data is loaded via d3.csv, aggregated from 15-minute intervals into hourly totals using d3.group, and the chart auto-fits to the window size. Tooltips display the generator name on hover.
