{"version":"1.0","type":"rich","title":"Activity6_Question3","description":"This interactive scatter plot shows the relationship between square footage and price for real estate listings across multiple cities, with each city assigned a distinct color in a legend. Built with D3 v7 and SVG, the visualization includes labeled axes and hover tooltips that display property details. The code uses `d3.csv` to load the in-memory data, `d3.scaleLinear` for both axes, and `d3.scaleOrdinal` with `d3.schemeSet2` for city-based coloring. Circle elements represent individual properties, and mouseover events trigger a transition-based tooltip update.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d4361cd187948e0a1a6cdab7a9c25d3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
