{"version":"1.0","type":"rich","title":"question 2","description":"This example demonstrates how to create a stacked area chart using D3.js, visualizing fruit quantities across multiple years. The chart renders three overlapping areas representing apples, oranges, and bananas, with color-coded fills from the `d3.schemeCategory10` palette. The code imports data from a remote CSV file, uses `d3.stack()` to compute stacked series, and applies `d3.area()` with `d3.scaleBand()` and `d3.scaleLinear()` to generate the SVG paths. Axes and labels are added using `d3.axisBottom()` and `d3.axisLeft()`, with hover-free static rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba22b80522514db681a8539a5116ac43?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
