{"version":"1.0","type":"rich","title":"Stream graph","description":"This interactive stream graph visualizes quarterly median house and unit prices in Sydney from 2007 to 2019, using a silhouette layout to show price trends across seven property categories. Built with D3 v5 and SVG, it loads CSV data and uses `d3.stack` with `stackOffsetSilhouette` to generate layered areas, while `d3.scaleOrdinal` and `d3.schemeDark2` handle coloring. Users can drag sortable buttons to reorder series, and hovering over an area highlights it and displays its name. The chart includes a customized time axis with tick marks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c29e85725d8b47b28f97cf2284269253?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
