{"version":"1.0","type":"rich","title":"shiftFFT of tremor analysis","description":"This example visualizes a Fast Fourier Transform (FFT) of tremor analysis data, displaying the double-sided magnitude spectrum of heart rate samples. The x-axis shows frequency in Hertz, while the y-axis displays raw magnitude values. The visualization uses a standard line chart rendered with d3.select and d3.line, with axes generated by @drbagwell/responsive-viz-axes. The data is processed through a custom radix-4 FFT implementation in fftClass.js, which computes the transform and completes the spectrum before plotting magnitude values against frequency.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0112dba5b174c45954b41de60615bd0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
