Two line charts compare the y1 and y2 series against a shared x-axis, with green step curves and red natural curves drawn via d3.line and distinct curve interpolators. Each series has its own left and right y-axis scales created with d3.scaleLinear and d3.axisLeft/axisRight, while a third band axis lists operation labels from example.tsv, rotated for readability. The visualization uses d3.tsv to load the tab-separated data and renders SVG circles and paths for each point. Axis ticks for operations are staggered using the scaleBand step.
