{"version":"1.0","type":"rich","title":"Question2","description":"This example shows a comparative area chart of monthly sales for two products during 2023, filled with distinct colors from a categorical scheme. The chart uses D3 v7’s `d3.scaleBand` for the month axis and `d3.scaleLinear` for the sales axis, with area paths generated via `d3.area`. Data is fetched as CSV from a GitHub repository, parsed with `d3.csvParse`, and rendered as SVG. A custom HTML legend, built with `d3.select` and `d3.selectAll`, displays color swatches and product labels alongside the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c40f5d49c8446a6b5df594cb72f2f07?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
