{"version":"1.0","type":"rich","title":"hw6_me","description":"This visualization shows a ThemeRiver chart tracking median house sale prices over time, segmented by property type and bedroom count. Seven categories—ranging from two-bedroom houses to three-bedroom units—are displayed as colored streams that flow and stack vertically. The chart uses D3 v6 with `d3.stack` and `stackOffsetSilhouette` to create the silhouette layout, while `d3.scalePoint` and `d3.area` handle the temporal axis and stream paths. Data comes from a CSV file containing quarterly sale prices, with each category assigned a distinct color from a ordinal scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b76cb549a33f4f85845348311da2e226?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
