{"version":"1.0","type":"rich","title":"interactive line chart","description":"This interactive line chart displays a time series of values over twelve months, with a circular marker at each data point. Hovering over a circle highlights it in red and reveals a tooltip showing the exact value, along with a dashed vertical line connecting the point to the x-axis. The visualization uses D3 v4 with an SVG canvas, employing `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, and `d3.axisBottom`. It loads external CSV data from a gist, parses dates with `d3.timeParse`, and animates the hover transitions with `transition().duration()`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-234738c6dcec661b10c65b1919f0ba07?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
