{"version":"1.0","type":"rich","title":"Area Chart","description":"This area chart visualizes global ozone-depleting substance emissions from 1960 to 2014, drawn with D3 v5 as an SVG. It uses `d3.scaleLinear` for both axes, `d3.axisBottom` and `d3.axisLeft` with gridlines, and a `d3.line` plus `d3.area` generator with `curveBasis` to create a smoothly filled purple shape beneath the line. The data is loaded from a CSV via `d3.csv` and rendered after coercing year and emission values to numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e301b3c8cca4f5fb6b410df94352b42?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
