This line graph shows metric values over time, with labeled axes and a tooltip that displays details on hover. Using D3.js, it plots data points for a service's RTS breaches across several weeks in 2022. The chart renders as an SVG with a steelblue line, and includes a tooltip element appended to the graph container. The x-axis displays dates formatted with `d3.timeFormat`, while the y-axis shows metric values. Data comes from a static dataset containing timestamp and value fields.
