{"version":"1.0","type":"rich","title":"7q3","description":"This example visualizes life expectancy across countries as a line chart, with each country plotted along the horizontal axis and life expectancy on the vertical axis, which is fixed between 60 and 90 years. The chart is rendered as an SVG using D3 v7, fetching CSV data from a GitHub gist. The code uses `d3.csvParse` to load the data, `d3.scaleBand` and `d3.scaleLinear` for positioning, and `d3.line` to draw the path. Axis labels are rotated for readability, and the line is styled in steelblue.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1bbb298c9cf34c86ac573048c4094061?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
