{"version":"1.0","type":"rich","title":"6","description":"This visualization uses a streamgraph to display median house sale prices over time, broken down by property type and number of bedrooms. A dropdown menu allows the user to select which stream is sorted at the top of the graph. The stacked areas are rendered as SVG paths using `d3.area` with a `stackOffsetSilhouette` layout, and the x-axis encodes time as years with seasonal divisions. Hovering over a stream reveals a tooltip with the price for that date, calculated from the stack’s bounds. The data comes from a CSV file (`ma_lga_12345.csv`) listing sale dates and median prices.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/be20c8c87faf485188742918e94cfe7e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
