{"version":"1.0","type":"rich","title":"fresh block","description":"A line chart displays monthly values for categories A through L, using a purple stroke on a light gray background with labeled axes and hover interactions. The chart includes a focus circle that appears on mouseover, with dashed hover lines tracing the x and y positions, while value labels and date annotations appear near each data point. The visualization is built with D3 v4, using `d3.scaleTime` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.line` to generate the path. Data comes from a JSON file with `name`, `value`, and `date` fields, rendered as SVG elements within a fixed 960×500 canvas.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-046585e23b8ebc7a07013360231736e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
