{"version":"1.0","type":"rich","title":"Fork","description":"This visualization plots earthquakes from the past week, sourced from the USGS GeoJSON feed, showing magnitude against time. Circles are colored by depth category (shallow, intermediate, deep) via a color legend, and hovering over legend items dims unrelated points. A brushX interaction allows selecting a time range, which highlights corresponding earthquakes with a darker stroke. The code uses D3 v7 for scales, axes, and the brush, alongside a ResizeObserver for responsive sizing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d444d08e8a194686987fee23421bd14e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
