{"version":"1.0","type":"rich","title":"Activity_7.2","description":"This area chart compares export values for China and the USA over time, using semi-transparent light blue and light green filled regions to show the trends for each country. The visualization is built with D3.js v7 and renders to SVG, using `d3.area()` to generate the stacked-looking paths and `d3.scaleLinear()` for the axes. Data is loaded from a remote CSV file and parsed before being mapped to the x-axis (year) and y-axis (exports in billion USD).","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c090e90db1a74922aeade2608c38951a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
