This multi-line chart visualizes engine speed (in RPM) over time, using time-series data sampled every two seconds from June 27, 2023. The chart displays RPM values that rise steadily from zero to a plateau at 250 RPM. Built with D3 v5, the visualization renders an SVG with zoom and pan functionality via `d3.zoom`, and includes a clip path to constrain the line within the chart boundaries. The chart is initialized through a custom `initializeChart` function that sets up the chart container, margins, and zoom behavior.
