This line chart visualizes wind speed profiles from HALO Photonics pulsed doppler LiDAR atmospheric remote sensing data, showing wind speed across altitudes up to 1200 meters. The visualization plots wind speed on the x-axis against altitude on the y-axis, using d3.line and d3.scaleLinear to generate the line path. Circles render individual data points with customizable radius and opacity, while a gray inner rectangle highlights the plotting region. The chart supports responsive resizing through @drbagwell/responsive-viz-axes and d3.observeResize, with axes labeled for wind speed (m/s) and altitude (meters).
