{"version":"1.0","type":"rich","title":"interactive line chart","description":"An interactive line chart displays monthly values from a small dataset, with pink circular markers for each data point and a black polyline connecting them. Hovering over a circle highlights it in red, reveals its value in a tooltip, and draws a dashed vertical line from the point to the x-axis. The visualization uses D3 v4 APIs including `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, `d3.axisBottom`, and `transition.style` for the hover effects. Data is loaded from a JSON file and rendered as SVG, with axis labels shown at the bottom.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-53204088cd83478643435c9551d00370?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
