{"version":"1.0","type":"rich","title":"D3-6: Area Charts 2","description":"This area chart visualizes world population from 1960 to 2015 using a time-series line graph. The visualization is built with D3 v7, using `d3.area()` with a basis curve to create a filled area beneath the line, while `d3.axisBottom` and `d3.axisLeft` render gridlines and formatted tick labels. The chart loads CSV data from a VizHub dataset and renders to SVG, with a steel-blue stroke and blue fill for the area.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/84c13566b759482b9b7ad1a5b9671225?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
