{"version":"1.0","type":"rich","title":"Fork of FFT-tremor-analysis","description":"This visualization displays the frequency spectrum of a single signal, the heart rate data, after applying a Fast Fourier Transform (FFT). The chart plots frequency bins against the raw magnitude, showing the signal's energy distribution across frequencies. The code implements a custom radix-4 FFT class, then uses D3.js functions including `scaleLinear`, `extent`, and `line` to render the plot, with axes from `@drbagwell/responsive-viz-axes`. The data is sourced from `@drbagwell/tremor-analysis-data`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cabd2da9cb9f4819855f62a322e4c83d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
