{"version":"1.0","type":"rich","title":"London Airbnb Person Cap vs Price w/ Color & Interaction","description":"This interactive scatterplot visualization explores London Airbnb pricing by person capacity, with user-selectable X and Y axes from multiple numeric property columns. The chart renders a density heatmap background using d3.scaleLinear, d3.scaleBand, and d3.scaleLog, computing per-pixel point density across the plot area and coloring regions from blue to yellow based on concentration. A yellow-to-blue gradient legend displays density levels with a red line marking the average. Users can filter data by minimum value via a range slider tied to any selected numeric property, with all controls updating the React-rendered visualization in real time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f72935e7972344f5b31d38b78164c6fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
