{"version":"1.0","type":"rich","title":"multi-line test","description":"This example displays a multi-line chart tracking a single time series dataset from 1750 onward, with each year’s value plotted as a point on an SVG canvas. The visualization uses d3.v4 to generate the line path and adds a hover interaction with a tooltip and a Voronoi overlay for precise mouse tracking. The chart includes context lines and a focus highlight on hover, with all rendering handled via SVG elements and D3’s data-binding methods.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-0c817e6f998c45ca6a97568c79c235c6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
