{"version":"1.0","type":"rich","title":"Fork of Line Chart (ICE 7)","description":"This visualization shows BMW car sales volumes aggregated by year from an external CSV dataset, displaying a line chart with circular data points. The code uses D3 v7 with an SVG rendering approach, applying `d3.csv` for data loading, `d3.rollup` for aggregation, and `d3.line` to generate the orange line path. Interactive tooltips appear on mouseover using DOM events and a styled div, while grid lines and axes are created with `d3.axisLeft` and `d3.axisBottom`. The implementation includes linear scales for positioning and an animation showcase via transitions on tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/17e6afb74bdf4ccfb4e5753b83f86eba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
