{"version":"1.0","type":"rich","title":"FFT-tremor-analysis","description":"This visualization applies a Fast Fourier Transform (FFT) to heart rate data from the `@drbagwell/tremor-analysis-data` package, displaying the resulting magnitude spectrum as a black line plot on a gray background. Using a custom `FFT` class with a radix-4 implementation, the code transforms 512 samples into frequency bins, plotting magnitude against frequency via d3's `scaleLinear` and `line` generators. Axes are rendered with `@drbagwell/responsive-viz-axes`, with the x-axis labeled \"Frequency (Bins)\" and the y-axis \"Raw Magnitude\".","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6d4c22dc90074178847bc49ce65c4472?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
