{"version":"1.0","type":"rich","title":"DFT and FFT Implementation","description":"This visualization compares the Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT) algorithms for spectral analysis. It plots frequency peaks of sine wave data, showing signal amplitude against frequency to reveal the dominant frequencies in a combined test signal. The implementation includes custom JavaScript classes for both transforms, using typed arrays for performance, and renders the results as a line chart with D3.js scales and axes. The visualization also includes a basic Fourier transform implementation for calculating the power spectrum.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b5313ca251bd42fd985c39e5cb3b2e46?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
