This visualization displays the power spectrum of wind speed data from the CSAT3A 3-D Sonic Anemometer. It uses a Fast Fourier Transform (FFT) to convert a 10-minute sample of the Uy wind component into frequency-domain magnitudes, plotted as decibels against frequency in Hertz. The custom FFT implementation computes the transform, and d3’s `scaleLinear`, `line`, and axes helper functions render the resulting spectrum on a gray plot area. Data comes from the `@drbagwell/csat3-data-file` package.
