{"version":"1.0","type":"rich","title":"Activity6_task3","description":"This example shows the relationship between car price and mileage with an interactive scatter plot. Each circle represents a vehicle, positioned by mileage on the x-axis and price on the y-axis, with color encoding price ranges via a `d3.scaleThreshold` (green, yellow, orange, red). Hovering over a point enlarges the circle and reveals the make, model, and price in a temporary text tooltip. The chart uses `d3.csv` to load external data and renders axes and circles as SVG, with a legend summarizing price bins.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a2dacb1a1134bf9bc1713ad7372db03?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
