{"version":"1.0","type":"rich","title":"contours with audio","description":"This example visualizes the distribution of randomly generated points as animated contour lines that respond to audio frequency data. The code uses D3's `contourDensity` and `geoPath` to compute and render density contours, while an AudioContext analyzer extracts frequency data to drive point movement in real time. Points are rendered as small steelblue circles, and the contour paths update dynamically as points shift based on the audio input. The visualization demonstrates how D3 can integrate web audio APIs with geographic projection techniques for interactive, sound-reactive data displays.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/69e4b388b07d441baa8759fbf16df21e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
