{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays US earthquake counts by region from 2011 to 2015, using data from the Data Canvas - Sense Your City project. Multiple colored lines represent different regions, with circles marking individual data points. The visualization uses d3.nest to aggregate and rollup data, d3.scaleTime for the x-axis, d3.scaleLinear for the y-axis, and d3.line with curveBasis for path generation. A color legend is rendered using a custom colorLegend module, and the chart includes interactive mouseover and mouseout events on the data circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ed38043b422e4ba9b5a49c2de7119874?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
