{"version":"1.0","type":"rich","title":"Interactive Visualization (Two Menus) - Earthquake Data","description":"This interactive visualization presents earthquake data from the 20th century through a bar plot and a world map. Two dropdown menus allow users to filter the data by start and end year, updating both the bar chart of regional death tolls and the map’s earthquake locations. The map uses `d3.geoPath` with a Mercator projection to render country outlines, while circle radii encode the Richter scale magnitude. The bar chart employs `d3.scaleBand` and `d3.scaleLinear` for axes, with tooltips providing country names on map hover. Visualizations render in SVG with smooth transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b7235be55f544d108affb47ca80fbb16?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
