{"version":"1.0","type":"rich","title":"population line area","description":"A line area chart displays world population by year, with a maroon filled area beneath a smooth curve and labeled axes for year and population count. The visualization uses D3 v5 with SVG rendering, employing `d3.scaleTime`, `d3.scaleLinear`, `d3.area`, `d3.curveBasis`, and `d3.axisLeft`/`d3.axisBottom` to generate the chart. Population data is loaded from a CSV file hosted on VizHub, with values converted to numbers and years parsed as dates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1e7f2f023ced4eb5b4b5b54ea90ba9dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
