This interactive scatter plot displays the CMAPSS aero-engine dataset, with time on the x-axis and a user-selected variable (altitude, Mach, TRA, or T2) on the y-axis. Users filter the data by unit and cycle via dropdown menus. Built with React and D3 v7, it renders SVG circles for each data point, using D3's scaleLinear for axes and extent for domain calculation, with tooltips showing exact values on hover.
