{"version":"1.0","type":"rich","title":"Interactive Visualization (Brush) - Earthquake Data","description":"This interactive visualization presents earthquake data from the 19th century through three coordinated views: a bar plot of deaths by region, a world map with circles sized by Richter magnitude, and a scatter plot correlating year, magnitude, and deaths. A brush interaction on the scatter plot filters the year range across all views. The map uses d3.geoMercator projection with d3.geoPath to render country boundaries from a GeoJSON source, includes a magnitude legend, and displays country names via tooltips on mouseover. The charts are built with D3 v7 APIs including scaleBand, scaleLinear, and the join operator.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c51fe87e3c5d48a4b5794ec903f35da4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
