This visualization demonstrates a Gantt chart for tracking equipment status and alarms. It displays time-based intervals for machine states, such as "Running" and "Engineering," alongside alarm events, using a custom `Gantt` function built with d3.v7. The chart renders SVG elements with adjustable row heights, lane labels, and reference lines, using `d3.scaleTime` for the x-axis. Data comes from CSV files containing state changes and alarm logs.
