{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows a stacked area chart of house and unit sales over time, with the MA (moving average) values across seven property types. The chart uses a silhouette offset, centering the data around zero. A list on the side enables the user to reorder the stacking sequence, and the chart redraws accordingly. It is built with D3.js, using `d3.stack`, `d3.area`, `d3.scaleTime`, and `d3.scaleOrdinal`. The data comes from a CSV file loaded via `d3.csv`, and hover interactions highlight individual areas with a tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b0f1868ca4314e58a3f16051fd52298d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
