{"version":"1.0","type":"rich","title":" vehicles Line Chart","description":"This line chart shows the average price of vehicles across different years, highlighting overall price trends over time. The visualization uses a blue monotone curve with circular markers for each year's data point, and hovering over a point reveals the exact year and average price in a tooltip. Built with D3.js (v7.8.5), it loads CSV data from a GitHub gist, groups and aggregates entries by year using `d3.rollup` and `d3.mean`, and renders the result as an SVG with axes using `d3.axisBottom` and `d3.axisLeft`. Grid lines and formatted y-axis labels (in thousands) help contextualize the price values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c58eca3c62a499b9b400e2db93170b5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
