{"version":"1.0","type":"rich","title":"Homework 6","description":"This interactive ThemeRiver chart visualizes median house prices over time, segmented by property type and bedroom count, using data from `ma_lga.csv`. The stacked streamgraph renders as SVG paths generated with `d3.area()` and `d3.curveBasis`, with colors from `d3.scaleOrdinal(d3.schemeTableau10)`. Users can click side labels to hide streams, hover to display a tooltip with date and price via `d3.pointer`, and click two streams to swap their stacking order, triggering an animated re-render with `d3.flatGroup` and `d3.minIndex`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea6d9e53510546f591d6bb87662f90ce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
