{"version":"1.0","type":"rich","title":"?","description":"This example shows a line chart of population values from 2005 to 2015, drawn as an SVG path using D3 v4’s `d3.line` and `d3.scaleTime`/`d3.scaleLinear` scales. The data is loaded from `data.json` with `d3.json` and parsed via `d3.timeParse`. A hover interaction uses a transparent overlay rectangle, `d3.mouse`, and `d3.bisector` to find the nearest year, then updates a focus circle, dashed hover lines, and a value label via direct SVG attribute manipulation. The y-axis labels are formatted in thousands with a custom tick format.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d4710dd36e5e468baf59646b819491bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
