{"version":"1.0","type":"rich","title":"line chart","description":"This line chart visualizes global population trends from 1970 to 2022 by summing yearly population figures across all countries in the world_population.csv dataset. The visualization uses D3 v7 with SVG rendering, employing `d3.csv` and `d3.autoType` for data loading, `d3.scaleLinear` for both axes, and `d3.line` with `curveMonotoneX` for the smoothed line path. Orange circles mark individual data points, with tooltips showing exact year and population values via appended `<title>` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f2410d99f1154c3a9e2b9abd49c1fc61?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
