{"version":"1.0","type":"rich","title":" tremor analysis with FFT & DFT classes","description":"This example shows the magnitude spectrum of a heart-rate tremor signal, plotting frequency bins on the x-axis against raw FFT magnitude on the y-axis. The visualization uses a line chart over a gray inner rectangle with labeled axes, generated from 512 samples taken at 62.5 samples per second. The code implements the Fast Fourier Transform via the `@drbagwell/dft-fft-fourier-analysis` library, then renders the result using D3 scales and line generators. Axes and labels are handled by the `@drbagwell/responsive-viz-axes` module.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/80986209b3174c7a9205bc3835aa15e2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
