{"version":"1.0","type":"rich","title":"double sided FFT","description":"This visualization demonstrates the results of a Fast Fourier Transform (FFT) applied to real-world wind data from a CSAT3 sonic anemometer, specifically the vertical wind component (Uy_1). It plots signal amplitude against frequency, revealing the dominant frequency peaks of the underlying sine wave patterns.\n\nThe example uses a custom `FourierTransform` function to decompose the time-series data, then renders the results as a line chart with D3.js (v7.9.0). The `viz.js` module uses `scaleLinear`, `line`, and `extent` from D3 to create a line path, with axes and labels handled by the `@drbagwell/responsive-viz-axes` library. The data is visualized through a simple line mark, with a grey inner plot area and circular data points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/235a8f0723a7406ead5e7fc57ed40c5b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
