{"version":"1.0","type":"rich","title":"single sided of tremor analysis","description":"This visualization displays the single-sided frequency spectrum of a tremor analysis, plotting raw magnitude against frequency in Hertz. The code loads heart rate data from an external package, applies a radix-4 Fast Fourier Transform via a custom FFT class, and computes magnitude values from the resulting complex array. Using D3.js with `scaleLinear` and a `line` generator, the chart renders on an SVG canvas with labeled axes and a gray interior rectangle. The y-axis shows raw magnitude, while the x-axis spans from zero to the Nyquist frequency.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f21c4e1673fd4851b01af822c56ebd66?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
