A parallel coordinates plot visualizes U.S. border and interior arrest data from 2014 to 2025, with each colored line representing a fiscal year across axes for total quantity, border arrests, interior arrests, convicted criminals, and non-criminals. Built with D3.js v7, the SVG renders axes and polylines colored via a categorical scale, supporting interactive hover and legend-click highlighting through d3.select and event listeners. The dataset, loaded via d3.csv, filters out earlier incomplete years, and the tooltips highlight individual year trajectories without altering the underlying scale.
