{"version":"1.0","type":"rich","title":"Fork of Area chart","description":"This area chart visualizes the total borrow count of library books per year. The data is loaded from a CSV file hosted on GitHub and aggregated by year. The chart uses a soft blue filled area with a line overlay and circular markers to emphasize data points. Hovering over a point reveals a tooltip. Built with D3 v7, it uses methods like `d3.area`, `d3.line`, `d3.csvParse`, and `d3.rollup` to process the data and render SVG elements. Grid lines and labeled axes provide context for the temporal trends.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d38873976bc44faa96dc4431b45bbfe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
