{"version":"1.0","type":"rich","title":"dataFFT","description":"This visualization demonstrates the Fast Fourier Transform (FFT) by plotting the frequency spectrum of a signal, showing a scatter plot of frequency peaks against their amplitudes. A CSV file containing signal data is fetched and processed through a naive Fourier transform algorithm, which calculates the real and imaginary components, amplitude, and phase for each frequency bin. The resulting data is rendered as a line chart of amplitude versus frequency using D3's `scaleLinear`, `line`, and `extent` functions, with axes and labels configured via the `@drbagwell/responsive-viz-axes` library. The visualization includes a gray inner plotting area and a black line trace, illustrating the spectral content of the input signal.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d5f7aeaeea2649feae3cd76f293f5422?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
