{"version":"1.0","type":"rich","title":"Activity7_task2","description":"This example visualizes car sales data with two charts. The first is an area chart of selling price over time, using a time-based x-axis and a linear y-axis. The second is a smoothed line chart showing the average selling price aggregated by 10,000-mile odometer intervals. Both charts are rendered as SVG using D3’s `select`, `scaleTime`, `scaleLinear`, `area`, `line`, `curveBasis`, and `mean` APIs. The data is loaded from a remote CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eefa476c880b486bb524dd0ffaa7a340?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
