{"version":"1.0","type":"rich","title":"dspFFT","description":"This visualization demonstrates the Fast Fourier Transform (FFT) applied to a composite signal of three sine waves at 40, 15, and 25 Hz. It displays the frequency spectrum as a line chart, showing amplitude peaks at the corresponding frequencies, alongside axes labeled \"Frequency Peaks of Sine Waves\" and \"Signal Amplitude.\" The code generates test data using a custom `sineGenerator`, computes the FFT with algorithms from `DSP.js` and `fourier.js`, and renders the result via D3 scales, line generator, and axes within an SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4451a452e5e74ecab9a40860f43b97d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
