{"version":"1.0","type":"rich","title":"cartographic doodled","description":"This example visualizes the Old Faithful geyser dataset through an animated, hand-drawn aesthetic. The visualization represents eruption durations and waiting times as a moving contour map, with lines that shift and deform over time. Using D3.js version 7, the code employs `d3.contourDensity` to generate density contours from the data points, then animates these contours with `transition.attrTween` to create a flowing, organic movement. The rendering uses SVG paths with a rough, sketch-like stroke style, giving the data a playful, doodled appearance.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27eac26dec8a42ec91327a7f980002ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
