{"version":"1.0","type":"rich","title":"Fork of Line Chart","description":"This fork of a line chart by priyankachary1701 visualizes total book borrow counts per publication year, drawn from a CSV of library books. The D3 v7 code fetches the data, rolls it up by year with `d3.rollup` and `d3.sum`, then renders an SVG line and points. The chart includes axes, gridlines, and a hover tooltip, using D3 scales (`scaleLinear`), `d3.line`, and the selection API alongside `d3.csvParse` for data ingestion.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b355b7c80b7c4890ba74c37ec6fa07f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
