{"version":"1.0","type":"rich","title":" single sided magnitude spectrum tremor analysis","description":"This visualization displays the single-sided magnitude spectrum of a tremor analysis signal, plotting frequency in Hertz against magnitude in decibels. The chart uses a logarithmic x-axis scale to show the frequency distribution of heart rate data sampled at 62.5 Hz. The code calculates a Fast Fourier Transform using a custom FFT class and visualizes the resulting magnitudes with D3.js, including axes and a line path. The visualization uses a custom `viz` function that applies log and linear scaling to map data points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8dc6de097ed048c9b16e6e813e41d87a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
