{"version":"1.0","type":"rich","title":"question 2","description":"This example shows a stacked area chart that visualizes fruit quantities (apples, oranges, bananas) over time, with three semi-transparent colored layers representing each fruit category. The visualization uses D3.js v7 to load CSV data from a GitHub repository, then applies `d3.stack`, `d3.area`, and `d3.scaleBand`/`d3.scaleLinear` to compute and render the stacked areas as SVG paths. Axes with year and quantity labels are added via `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fbd46e502c7442bea0494abbc02ae8bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
