{"version":"1.0","type":"rich","title":" FFT-tremor-analysis-hz","description":"This visualization displays a single-sided magnitude spectrum of heart rate tremor data, showing frequency components on the x-axis against raw magnitude on the y-axis. It applies a radix-4 FFT implementation from a custom `FFT` class to 512 samples of heart rate data, then plots the computed magnitudes as a line chart. The visualization uses D3.js scales, line generator, and responsive axes from `@drbagwell/responsive-viz-axes`, with the frequency axis calibrated using a sampling rate of 62.5 Hz.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/83fbb8b231ed422d8885fbf13d7e9637?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
