{"version":"1.0","type":"rich","title":"Spectrogram Visualization","description":"This spectrogram visualization renders audio frequency data as a series of colored rectangles across an SVG canvas. The code loads a CSV file containing 13 numeric columns representing frequency bins and maps each row to a rectangular band using D3’s data join. The example uses d3.csv for data loading, d3.scaleLinear for horizontal positioning, and d3.select to manipulate the SVG elements. The rectangles are appended with a fixed height, though the width calculation appears incomplete in the code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/56d8c6a1a1e44bc396497f3c7bad2fcc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
