{"version":"1.0","type":"rich","title":"ice7_task2_2","description":"This line chart visualizes the average car price per year, using data from a CSV file loaded via `d3.csv`. The code groups the data by year using `d3.rollups` and computes the mean price, then renders a monotone-curved line via `d3.line` with `d3.curveMonotoneX`. Orange dots mark each year’s average, with hover tooltips. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, and the SVG chart includes labeled axes for year and average price in USD.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b712030857274fd4aa9740a14b031861?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
