{"version":"1.0","type":"rich","title":" FFT of tremor analysis","description":"This example displays the double-sided magnitude spectrum of a tremor analysis, plotting frequency in Hertz against raw magnitude as a connected line chart. The code processes 512 heart rate data points through a custom FFT implementation, then visualizes the resulting complex spectrum using d3.js scales, axes, and a line generator. The visualization updates responsively with the container size, using a gray inner plot area with labeled axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1cd0a65e4ff94274a39e51be5d6b4f63?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
